bug#71504: 30.0.50; FR: Fix suggestions ("quick fix") for Flymake diagnostics

[Eshel Yaron]

Following a recent short discussion[0] on emacs-devel, I'm opening this
feature request so it doesn't get lost:

Flymake should provide a standard way for backends to associate fix
suggestions with the diagnostics they produce, along with a
backend-agnostic user interface (e.g. a command) for examining and
applying such fixes.

I suggested a possible implementation that works quite well for me
(with the three backends I've adapted so far - checkdoc, shellcheck
and Eglot), but any other solution that gives various backends a
standard way to provide their fixes would be just as welcome.


Thanks and best regards,

Eshel
