bug#12174: 24.1.50; C-h f and non-symbol remap targets

[Christopher Schmidt]

(global-set-key [remap write-file] (lambda () (interactive) 'rms))
C-h f write-file RET

This yields in an error because help-fns--key-bindings expects
(command-remapping 'write-file) to be a symbol.

Here is a patch that abbreviates non-symbol remap targets with "??".
This is consistent with what describe-bindings displays.

A sobering thought - ?? does not need to be quoted.

Actually, ?? is a bad choice, since it seems to imply that Emacs doesn't
even know what it's remapped to, whereas Emacs does know very well, it
just doesn't want to print it out in full because it would be ugly and
too verbose.
So I suggest we replace "??" with something like "an anonymous command".

Thanks; applied to trunk.

One question: If some other severe bug arises upon the (not yet)
released Emacs 24.2, so that a 24.3 release becomes necessary (from
the emacs-24 branch), then the above tag will be incorrect, won't it?

It seems that the current versioning pattern has this problem. We
don't know beforehand the version under which the current trunk code
will be released.

So, what about switching to a different pattern which doesn't have this problem?

For example: Name the next trunk's branch as "emacs-24.3", and every
release made from that branch would be labeled "emacs 24.3.x".

This way, we would know for sure that the trunk code would be released
as version "24.4" (or "25.1" -- what the maintainer's decide).

Yes, it's a (minor) problem. I suggest discussing it on emacs-devel
rather than here though.
