bug#55301: 27.2; RFE: Auto-create defcustom for declared minor mode keymap

[Phil Hudson <phil.hudson@iname.com>]

Not a built-in one, no, but it is not difficult to construct a composite
defcustom.  There are plenty of sequence types and a keybinding type to compose
with.

Perhaps Emacs *should* have a standard built-in keymap defcustom type, but that
would be the subject for a separate RFE.

What I am proposing is something along the lines of this: when a mode (major or
minor, it's strictly irrelevant) declares a keymap, part of the processing of
the expansion of the mode definition should include a defcustom enabling the
user to customize that keymap using the Customize UI, rather than (only) by
writing elisp code.  In other words, where foo-mode-map is currently implemented
(I assume) using a defvar, that should change to a defcustom.  That's really all
I'm suggesting: change the defvar (or whatever) to a defcustom.
