Enhancement suggestion.
Recursive editing is sometimes useful. Its main disadvantage is that
you might not be aware that you've entered or exited a recursive edit.
Please consider adding something like what this code provides:
https://www.emacswiki.org/emacs/download/rec-edit.el
There are really two different features there. Either could be provided
on its own by Emacs. But `rec-edit.el' rolls them together in a minor
mode, `rec-edit-mode'.
1. You can use the same key, `C-M-c', to enter a recursive edit as to
exit. When already in a recursive edit, it exits or, if you use a
prefix arg, it enters a new recursive edit. In other words, it does
this:
(if (or (< (recursion-depth) 1)
current-prefix-arg)
(recursive-edit)
(exit-recursive-edit))
2. It optionally highlights the mode-line indication, `[...]', to make
clear that you're in a recursive edit, and to indicate the depth.
Whether this highlighting is done is controlled by a Boolean user
option.
Emacs generally discourages, or doesn't encourage, initiating a
recursive edit. That's understandable. But sometimes it's useful, and
a major reason it's discouraged is because it's easy for users to not
realize they're in a recursive edit, or not know how to exit.
This minor mode aims to mitigate those downsides. And it's off by
default, so presumably a user of it wants to make use of recursive
editing but wants to be aware when doing that.
I think something like this would be helpful for Emacs to provide.
