v3 (Custom function choice). Change interface of function choice in
Custom `:type' spec to support full `display-buffer' action parameter.
Cancel second patch focusing on frames-related display styles (work to
continue in a separate bug).

I've flip-flopped on this completely and have reverted back to favoring
the idea of having user implementations (and `function-item' offerings)
expect a full `display-buffer' action rather than just the alist portion
alone. As explained up thread, I originally figured it'd be easier on
users if we gave them just the alist to ponder rather than something
requiring destructuring and recomposing. But now I think it's cleaner to
sacrifice that minor convenience in favor of having folks mentally
associate these functions with `display-buffer', `pop-to-buffer', etc.,
since they roughly serve the same purpose (as opposed to the "action
functions" they consume).
Along with this U-turn, I think we ought to consider exporting the new
variable `erc--display-context'. I've left it internal, for now, but
making it public would allow folks with an existing collection of
`display-buffer' actions to write simple match predicates (for
`display-buffer-alist') that decide things based on calling context.

Actually, looking back on
bug#55540: 29.0.50; ERC launches autojoin-channels in current frame
which led to a change that's been on HEAD for two months now
https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=0e4c07dc
I've come to the belated realization that this feature is not all that
useful in and of itself. For whatever reason, I fixated on fulfilling
the requirements described in the bug without questioning whether that
alone would result in a satisfactory user experience. Indeed, after
actually trying out the feature from the perspective of someone wanting
to conduct all ERC-related business in a separate frame, merely offering
a display style oriented toward that end seems wholly insufficient.
For example, buffers spawned in other contexts, via related options,
such as `erc-receive-query-display', won't find their way to the correct
frame unless they've also been customized accordingly. Similarly, once a
buffer is correctly routed to a "dedicated" frame, it's unclear how the
user wants it displayed. I suppose we could affix existing options as
combined choices, like
`erc-use-existing-frame-buffer'
`erc-use-existing-frame-window'
`erc-use-existing-frame-window-no-select'
`erc-create-new-frame-buffer'
...
but that adds a lot of clutter and isn't great for maintenance. There's
also the issue of integrating with other modules, like `erc-track',
whose users likely want the mode line to only show changes for
associated buffers and C-SPC to limit its switching between those.
In sum, I think the basic idea of being able to marry new ERC buffers to
an ERC-managed frame is a good one, but it may be orthogonal to our
traditional idea of display styles. I'm now leaning toward exploring
something like a separate module to make the experience feel more
integrated and less bolted on. I therefore move that we revert the
change cited above in the meantime so people don't get used to it, and
then pursue a more comprehensive solution to frame-oriented
buffer-display styles in this (or some related) bug. Thanks.

Subject: [PATCH 1/2] Revert "Allow erc-reuse-frames to favor connections"
This (mostly) reverts commit 0e4c07dc7448aafd2aa5f6e101d7b7aac23d8a6b.
* etc/ERC-NEWS: Also revert hunk from 52c8d537 "* etc/ERC-NEWS: Add
section for ERC 5.6." because it announced this feature, which no
longer exists.
* lisp/erc/erc.el (erc-reuse-frames): Revise doc string instead of
reverting completely. (Bug#62833)

-** Easily constrain all ERC-related business to a dedicated frame.
-The option 'erc-reuse-frames' can now be set to 'displayed', which
-tells ERC to show new buffers in frames already occupied by buffers
-from the same connection. This customization depends on the option
-'erc-buffer-display' (formerly 'erc-join-buffer') being set to
-'frame'. If you find the name 'displayed' unhelpful, please suggest

** Module 'fill' can add a bit of space between messages.
On graphical displays, it's now possible to add some breathing room

Subject: [PATCH 2/2] [5.6] Allow custom display-buffer actions in ERC
* etc/ERC-NEWS: Mention new `display-buffer' "action" variant for all
buffer-display options.
* lisp/erc/erc-backend.el (erc-server-JOIN, erc-server-PRIVMSG,
erc-server-NOTICE): Set `erc--display-context' to a symbol for the IRC
command, like `JOIN' in order to influence `erc-setup-buffer' by way
of `erc--open-target'.
* lisp/erc/erc.el (erc--buffer-display-choices): New helper for
defining common `:type' for all buffer-display options.
(erc-buffer-display): Add new choice of either `display-buffer' or
`pop-to-buffer' paired with an "action alist".
(erc-buffer-display, erc-interactive-display, erc-reconnect-display,
erc-receive-query-display): Use helper `erc--buffer-display-choices'
for defining `:type'.
(erc-skip-displaying-selected-window-buffer): New variable, deprecated
at birth, to act as an escape hatch for folks who don't want to skip
the displaying of buffers already showing in the selected window.
(erc--display-buffer-action): Local variable allowing modules to
influence the displaying of new ERC buffers independently of user
options.
(erc-open): Bind `display-buffer-overriding-action' to the value of
`erc--display-buffer-action' around calls to `erc-setup-buffer'.
(erc-setup-buffer): Do nothing when the selected window already shows
current buffer unless user has provided a custom action. Accommodate
new choice values `display-buffer' and `pop-to-buffer'.
(erc-select-read-args): Add `erc--display-context' to environment.
(erc, erc-tls): Bind `erc--display-context' around calls to
`erc-select-read-args' and main body.
(erc-cmd-JOIN, erc-cmd-QUERY, erc-handle-irc-url): Add item for
`erc-interactive-display' to `erc--display-context'.
* test/lisp/erc/erc-tests.el (erc-setup-buffer--custom-action): New
test.
(erc-select-read-args, erc-tls, erc--interactive): Expect new
environment binding for `erc--display-context'. (Bug#62833)

+'bury'. An escape hatch for this and most other baked-in behaviors is
+now available in the form of a new type variant recognized by all such
