bug#51744: 29.0.50; void symbol emoji-describe

[Po Lu via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Starting from `emacs -Q', move point to any emoji in
admin/unidata/emoji-zwj.sequences, and do `C-u C-x ='.  You will get the
following error:

  describe-char: Symbol’s function definition is void: emoji-describe

Thanks.

Until ldefs-boot has been updated you probably have to say "cd lisp;
make autoloads-force" first.

Thanks, that worked.  And sorry for the noise.

FTR, all you need to do is copy a correct loaddefs.el over ldefs-boot.el
and commit the latter.

Oh, great -- I didn't know that.  I grepped for "ldefs-boot" in the tree
to see whether we had any instructions concerning that file, but I
didn't find anything.  (I did find the ./admin/update_autogen script,
and tried running it, but it failed here.)

Perhaps we should mention this somewhere?  But I'm not sure where --
CONTRIBUTE doesn't seem to be quite the right place.

loadup.el:185

What failed? If you have a clean tree, and run 'admin/update_autogen -L'
it will regenerate ldefs-boot.el

People who know, know, and people who donʼt know won't know where to
look (and then thereʼs me, who forgets, and has to go re-read
loadup.el 😊). CONTRIBUTE is better than not documenting it (although
maybe it should go in 'admin/release-process' as well).

Oh, right.  🤐

I tried it with no parameters -- I don't remember what failed.

I put the note into lisp/loaddefs.el itself (and thereby in
lisp/ldefs-boot.el), which should be even easier to find.

Yuck.
Now this note is also in:

./lisp/cedet/ede/loaddefs.el
./lisp/cedet/semantic/loaddefs.el
./lisp/cedet/srecode/loaddefs.el

and any loaddefs.el files outside the Emacs tree.
