i have new patch for allout.el. it fixes a few things:
- hooks and mode-specific variable settings are properly set to be local,
and properly cleaned up on mode deactivation
- auto-fill is not forced active if it wasn't already active when the mode
was initiated.
- hotspot key handling is modularized, for consistent use everywhere.
- a new hook variable, `allout-mode-deactivation-hook', provides a
complement to `allout-mode-hook'.
the settings cleanup is implemented with an improved settings
suspension/resumption mechanism, accompanied by some much needed unit
tests. the unit tests are run after the file is loaded if a new
customization option, `allout-run-unit-tests-after-load', is true.
the idea is that allout code developers set this to true, and are
warned quickly about regressions.
the change-log is included below and also attached. the patch and a
new version of the NEWS file are also attached. I'm hoping someone
with commit privileges will have a moment to install these changes.

* allout.el: Require 'cl.
(allout-mode-deactivate-hook): New hook, is run when allout mode
deactivates.
(allout-developer): New allout customization subgroup.
(allout-run-unit-tests-after-load): New allout-developer
customization variable, when true allout unit tests are run after
file load.
(allout-inhibit-auto-fill): Disable auto-fill activity even during
auto-fill-mode.
(allout-resumptions): Removed, to be replaced by...
(allout-add-resumptions): Register variable settings to be
reinstated by `allout-do-resumptions'. The settings are made
buffer-local, but the locality/globality of the suspended setting
is restored on resumption.
(allout-do-resumptions): Reinstate all settings suspended using
`allout-add-resumptions'.
(allout-test-resumptions): Unit tests (and intermediate variables)
for resumptions.
(allout-tests-globally-unbound, allout-tests-globally-true)
(allout-tests-locally-true): Intermediate variables for
resumptions unit tests.
(allout-overlay-preparations): Replaces `allout-set-overlay-category'.
(allout-exposure-category): Replaces 'allout-overlay-category variable.
(allout-mode): Use `allout-add-resumptions' and `allout-do-resumptions'
instead of retired `allout-resumptions'. For hook functions, use
`local' parameter so hook settings are created and removed as
buffer-local settings. Revise (resumptions) setting
auto-fill-function so it is set only if already active. (The
related fill-function settings are all made in either case, so
that activating auto-fill-mode activity will have the custom
allout-mode behaviors (hanging indent on topics, if configured for
it). Also, remove all allout-exposure-category overlays on mode
deactivation.
(allout-hotspot-key-handler): New function extracted from
`allout-pre-command-business', so the functionality can be used
for other purposes, eg as a binding in an overlay.
(allout-pre-command-business): Use new `allout-hotspot-key-handler'.
(allout-auto-fill): Respect new `allout-inhibit-auto-fill'
customization variable.
(allout-run-unit-tests): Run the (currently quite small)
repertoire of unit tests. Called from an eval-after-load statement
if user has customized `allout-run-unit-tests-after-load' non-nil.

in addition to `allout-view-change-hook'.
(allout-show-bodies, allout-old-style-prefixes)
(allout-stylish-prefixes, allout-use-hanging-indents): Quote the
lambda forms to prevent their showing up in variable help

(allout-numbered-bullet, allout-file-xref-bullet, allout-layout):
Use string-or-null-p to qualify safe-local-variable values.
(allout-reindent-bodies): Use memq to qualify matches against

symbols, use memq, and quote the lambda.
(allout-overlay-interior-modification-handler): Remove unused
variables `msg' and 'opened'.

* allout.el: Use allout invisible-text overlays instead of
selective display for concealed text. Also, lots of general
cleanup, and improved compatibility code.
(allout-version) Incremented, corrected, revised, and refined
module commentary.
(provide 'allout): Moved to the bottom, added a require of overlay.
(allout-encrypt-unencrypted-on-saves): Defaults to t instead of
`except-current'.
(allout-write-file-hook-handler): Minimize delay.
(count-trailing-whitespace-region): New function so
auto-encryption of current topic can resituate cursor exactly.
PGP/GPG encryption trims trailing whitespace from lines, which
must be accounted for across encryption then decryption.
(allout-command-prefix): Now defaults to "\C-c<space>" rather than
just plain "\C-c", to avoid intruding on user's keybinding space.
(allout-toggle-current-subtree-encryption): Pass along fetch-pass
parameter, so user request to provide a new password is done.

Refined mechanism for auto-filling behavior while in allout mode.
(allout-mode): Explicitly specify the mode map in the docstring.
Clarify provision for various write-file hook var names.
Adjusted for invisible-text overlays instead of selective-display.
(allout-depth): Really return 0 if not within any topic. This
rectifies `allout-beginning-of-level' and sequence numbering
errors that occur when cutting and pasting numbered topics.
Changed from a in-line subst to a regular function, as well.
(allout-pre-next-prefix): Renamed from allout-pre-next-preface.
(allout-end-of-subtree, allout-end-of-subtree)
(allout-end-of-entry, allout-end-of-current-heading)
(allout-next-visible-heading, allout-open-topic, allout-show-entry)
(allout-show-children, allout-show-to-offshoot)

to know when to close the containing topic.
(allout-pre-command-business, allout-post-command-business):
Simplify undo-batching and dynamic isearch exposure.
(allout-set-overlay-category): New for invisible-text overlays.
Sets properties of allout-overlay-category, used by
allout-flag-region to set invisible-text overlay properties.
(allout-get-invisibility-overlay): Get the first qualifying
invisibility overlay, so we can find the extent of it.
(allout-back-to-visible-text): Get to just before the beginnining
of the current invisibility overlay, if any.
(allout-overlay-insert-in-front-handler)
(allout-overlay-interior-modification-handler)
(allout-before-change-handler, allout-isearch-end-handler): New
functions to handle extraordinary actions affecting concealed
text.
(allout-flag-region): Use overlays instead of selective-display
for invisible text - by inheritence from the properties of
allout-overlay-category in mainline Emacs, and applied
property-by-property in XEmacs, some recent versions of which
don't inherit the properties from the category. Provisions to
respond to concealed-text edits simplified drastically.
(allout-isearch-rectification, allout-isearch-was-font-lock)
(allout-isearch-expose, allout-enwrap-isearch)

Ditched unused variables.
2005-12-02 Ken Manheimer <ken.manheimer@gmail.com>
* allout.el (eval-when-compile): Remove unnecessary load of cl.
Add fset of allout-real-isearch-abort during compile to fix
byte-compilation warnings.
(allout-mode-p): Move definition of this macro above all uses, or
byte compilation in barren emacs (eg, during emacs build) will
lack the definition.
(allout-mode): Move this variable above any uses, or byte
compilation will fail.
(allout-resolve-xref): Remove use of personal file-reference function.
(allout-toggle-current-subtree-encryption): Do the current (ie,
visible containing) topic, rather than nearest around point. Doc fix.

buffer local, make the write-file-hook activity contingent to
allout-mode.
(allout-mode): Use key-binding substitution in the docstring.
(allout-kill-line): Spell-out kill ring data structure mutation
instead of using byte-compiler-complaint-provoking `pop'.
(allout-insert-listified): Use `insert' rather than `insert-string'
(allout-toggle-current-subtree-encryption): Update docstring, adjust
to new gpp-based encryption, use new `allout-encrypted-topic-p'.

avoiding confusing "containment discontinuities".
(allout-reindent-bodies): Fix retention of body relative hanging
indent during promotion of collapsed bodies.
(allout-open-topic): Make it easy to open new topic with same
bullet as current topic - topic creation functions provided with
any universal argument provokes now prompt for bullet, defaulting
to the bullet of the previous topic.
(allout-plain-bullets-string, allout-distinctive-bullets-string):
Plain bullet alternates `.' period and `,' comma only. All other
bullets are relegated to special status (but customizable).
(allout-end-of-entry): Rename from allout-end-of-current-entry

** Changes in Allout
*** Topic cryptography added, enabling easy gpg topic encryption and
decryption. Per-topic basis enables interspersing encrypted-text and
clear-text within a single file to your heart's content, using symmetric
and/or public key modes. Time-limited key caching, user-provided
symmetric key hinting and consistency verification, auto-encryption of
pending topics on save, and more, make it easy to use encryption in
powerful ways.
*** `allout-view-change-hook' marked as being deprecated - use
`allout-exposure-change-hook' instead. Both are currently being used, but
`allout-view-change-hook' will be ignored in a subsequent allout version.
*** Default command prefix changed to "\C-c " (control-c space), to avoid
intruding on user's keybinding space. Customize the
`allout-command-prefix' variable to your preference.
*** Allout now uses text overlay's `invisible' property (and others) for
concealed text, instead of selective-display. This simplifies the code, in
particular avoiding the need for kludges for isearch dynamic-display,
discretionary handling of edits of concealed text, undo concerns, etc.
*** Many substantial fixes and refinements, including:
- repaired inhibition of inadvertent edits to concealed text
- repaired retention of topic body hanging indent upon topic depth shifts
- refuse to create "containment discontinuities", where a
topic is shifted deeper than the offspring-depth of its' container
- auto-fill-mode is now left inactive when allout-mode starts, if it
already was inactive. also, `allout-inhibit-auto-fill' custom
configuration variable makes it easy to disable auto fill in allout
outlines in general or on a per-buffer basis.
- new hook `allout-mode-deactivate-hook', for coordinating with
deactivation of allout-mode.
- bulleting variation is simpler and more accommodating, both in the
default behavior and in ability to vary when creating new topics
- mode deactivation now does cleans up effectively, more properly
restoring affected variables and hooks to former state, removing
overlays, etc.
- included a few unit-tests for interior functionality. developers can
have them automatically run after module w/customization option with
customization variable `allout-run-unit-tests-after-load'.
- many, many minor tweaks and fixes. many internal fixes and
refinements of docstrings.
- version number incremented to 2.2

From: Ken Manheimer @ 2006-07-08 16:31 UTC (permalink / raw)
just after posting my patch, i started catching up on emacs-devel
traffic and noticed the eval-after-load controversy. as i mentioned
in my posting, i use eval-after-load, conditioned by a customization
var. it makes sense to me to have my use of eval-after-load reviewed,
and get suggestions about how best to accomplish what i want.
the goal is that developers are informed as quickly possible when any
changes they make break the unit tests. i am using eval-after-load of
the file, itself, and it is evaluated only if the user has customized
`allout-run-unit-tests-after-load' to true, which should not generally
be the case. is this an ok use? (i could put the invocation of the
tests at the bottom of the file, but i prefer the provide to be at the
bottom.) i can make a new patch if this use is unruly.

i answered my own question. it's sufficient to have the unit tests
run (if user configured for it) as the second to last thing in the
file. attached is a new ChangeLog entry (and just the current entry,
this time), NEWS entry, and patch. everything is the same except the
tests are run towards the end of the file, instead of using
eval-after-load.
here's a copy of the ChangeLog entry, inline, as well:
2006-07-08 Ken Manheimer <ken.manheimer@gmail.com>
* allout.el: Require 'cl.
(allout-mode-deactivate-hook): New hook, is run when allout mode
deactivates.
(allout-developer): New allout customization subgroup.
(allout-run-unit-tests-on-load): New allout-developer
customization variable, when true allout unit tests are run towards
end of file load/eval.
(allout-inhibit-auto-fill): Disable auto-fill activity even during
auto-fill-mode.
(allout-resumptions): Removed, to be replaced by...
(allout-add-resumptions): Register variable settings to be
reinstated by `allout-do-resumptions'. The settings are made
buffer-local, but the locality/globality of the suspended setting
is restored on resumption.
(allout-do-resumptions): Reinstate all settings suspended using
`allout-add-resumptions'.
(allout-test-resumptions): Unit tests (and intermediate variables)
for resumptions.
(allout-tests-globally-unbound, allout-tests-globally-true)
(allout-tests-locally-true): Intermediate variables for
resumptions unit tests.
(allout-overlay-preparations): Replaces `allout-set-overlay-category'.
(allout-exposure-category): Replaces 'allout-overlay-category variable.
(allout-mode): Use `allout-add-resumptions' and `allout-do-resumptions'
instead of retired `allout-resumptions'. For hook functions, use
`local' parameter so hook settings are created and removed as
buffer-local settings. Revise (resumptions) setting
auto-fill-function so it is set only if already active. (The
related fill-function settings are all made in either case, so
that activating auto-fill-mode activity will have the custom
allout-mode behaviors (hanging indent on topics, if configured for
it). Also, remove all allout-exposure-category overlays on mode
deactivation.
(allout-hotspot-key-handler): New function extracted from
`allout-pre-command-business', so the functionality can be used
for other purposes, eg as a binding in an overlay.
(allout-pre-command-business): Use new `allout-hotspot-key-handler'.
(allout-auto-fill): Respect new `allout-inhibit-auto-fill'
customization variable.
(allout-run-unit-tests): Run the (currently quite small)
repertoire of unit tests. Called just before the provide iff user
has customized `allout-run-unit-tests-on-load' non-nil.

** Changes in Allout
*** Topic cryptography added, enabling easy gpg topic encryption and
decryption. Per-topic basis enables interspersing encrypted-text and
clear-text within a single file to your heart's content, using symmetric
and/or public key modes. Time-limited key caching, user-provided
symmetric key hinting and consistency verification, auto-encryption of
pending topics on save, and more, make it easy to use encryption in
powerful ways.
*** `allout-view-change-hook' marked as being deprecated - use
`allout-exposure-change-hook' instead. Both are currently being used, but
`allout-view-change-hook' will be ignored in a subsequent allout version.
*** Default command prefix changed to "\C-c " (control-c space), to avoid
intruding on user's keybinding space. Customize the
`allout-command-prefix' variable to your preference.
*** Allout now uses text overlay's `invisible' property (and others) for
concealed text, instead of selective-display. This simplifies the code, in
particular avoiding the need for kludges for isearch dynamic-display,
discretionary handling of edits of concealed text, undo concerns, etc.
*** Many substantial fixes and refinements, including:
- repaired inhibition of inadvertent edits to concealed text
- repaired retention of topic body hanging indent upon topic depth shifts
- refuse to create "containment discontinuities", where a
topic is shifted deeper than the offspring-depth of its' container
- auto-fill-mode is now left inactive when allout-mode starts, if it
already was inactive. also, `allout-inhibit-auto-fill' custom
configuration variable makes it easy to disable auto fill in allout
outlines in general or on a per-buffer basis.
- new hook `allout-mode-deactivate-hook', for coordinating with
deactivation of allout-mode.
- bulleting variation is simpler and more accommodating, both in the
default behavior and in ability to vary when creating new topics
- mode deactivation now does cleans up effectively, more properly
restoring affected variables and hooks to former state, removing
overlays, etc.
- included a few unit-tests for interior functionality. developers can
have them automatically run at the end of module load by customizing
the option `allout-run-unit-tests-on-load'.
- many, many minor tweaks and fixes. many internal fixes and
refinements of docstrings.
- version number incremented to 2.2
