the attached patch resolves a few stray bugs and provides a much
needed cleanup of the allout-mode docstring, which is the central
documentation for the mode. (the bug fixes are small - more than 4/5
of the patch is for the allout-mode docstring changes.)
the bugs resolved:
- depth accommodation for yanks containing multiple topics was broken
- viewing the mode docstring before the mode was first invoked
would fail to find any keybindings
the changelog is below and attached.

* allout.el (allout-ascend): Add an optional argument to preserve
original position of point when unsuccessful. Also, fix a
docstring error.
(allout-yank-processing): Fix depth shift of multiple-topic yanks
work again, using allout-ascend's new option.
(allout-setup-mode-map): Extracted from allout-mode to initialize
allout-mode-map. Call this function on file load, so the mode
docstring substitutions work even if allout mode has not yet been
invoked.
(allout-mode): Use new allout-setup-mode-map to track any
keybinding customizations since the map was last processed. Also,
refine the docstring so it's ship-shape for release.

Topic hierarchy constituents - TOPICS and SUBTOPICS:
-TOPIC: A basic, coherent component of an Emacs outline. It can

-CURRENT topic:
- The visible topic most immediately containing the cursor.
-DEPTH: The degree of nesting of a topic; it increases with
- containment. Also called the:
-LEVEL: The same as DEPTH.
+ITEM: A unitary outline element, including the HEADER and ENTRY text.
+TOPIC: An ITEM and any ITEMs contained within it, ie having greater DEPTH
+ and with no intervening items of lower DEPTH than the container.
+CURRENT ITEM:
+ The visible ITEM most immediately containing the cursor.
+DEPTH: The degree of nesting of an ITEM; it increases with containment.

ANCESTORS:

+PARENT: An ITEM's immediate ANCESTOR. It has a DEPTH one less than that

OFFSPRING:
- The topics contained by a topic;

SUBTOPIC:

I see that you changed several occurrences of ... ( ... ) ... to
.. \( ... \) ... in the doc string.
You only need to quote a ( in the rare case that it occurs in
the first column of a line, and you never need to quote a ).
Appendix D.6 of the Emacs Lisp Reference Manual says:
* If a line in a documentation string begins with an
open-parenthesis, write a backslash before the open-parenthesis,
like this:
The argument FOO can be either a number
\(a buffer position) or a string (a file name).
This prevents the open-parenthesis from being treated as the start
of a defun (*note Defuns: (emacs)Defuns.).

thanks for the tip - i've wondered about a few nuances concerning
escaping parens, and i might as well ask, while the issue is raised.
first, does it hurt to escape open parens excessively? i ask because
i deliberately tend to quote all leading opens, so i can flow
docstring paragraphs without worry about surprises. it would not be a
hardship to be more discriminating, but still wonder if there's a
drawback beyond the increased mystery (onions-in-the-varnish wise) of
unnecessary escaping.
i'm pretty haphazard about escaping the close parens, but decided to
shoot for consistency in this last edit - apparently in the wrong
direction. (i don't see any prohibition against escaping the close
parens, but i suppose it's more onions-in-the-varnish noise.) it would
be nice if there were a way to get paren matching for an escaped open
paren, and i gather there currently is no provision for that. is that
right?
just curious, mostly.

It looks sort of ugly, and teaches other people that all open parens
need to be escaped. Aside from that, it does no harm.

There is never any reason to do that, so please don't.
