Heads up: proposal to introduce `minibuffer-mode'.

[Alan Mackenzie]

Hello, Emacs.

In bug #47150, the OP has drawn attention to the inconvenience that the
fact of minibuffers running in fundamental mode causes.

For example, some minor modes maintain lists of major modes that they
are valid (or invalid) in.  If these minor modes wish to include/exclude
minibuffers, fundamental-mode is not really specific enough.

Therefore, I propose to create and use a new mode `minibuffer-mode' for
minibuffers, but without changing anything else (for example, the new
mode's key map would continue not to be used).

If anybody sees any problems here, or wishes to object for other
reasons, please contribute to the thread at 47150@debbugs.gnu.org.
