bug#10775: Feature request: avoid revert question in `find-file-noselect'

[Eli Barzilay]

The code in `find-file-noselect' will ask about reverting a buffer, a
question that pops up in several contexts that lead to that function.
When the question pops up, the buffer is still not visible so it's
hard to make a decision (perhaps some process changed the file and I'd
like to switch to the buffer to save its contents first?).

It would be nice if there was some option that would make it just
display a warning about the change -- so I know that I can now revert
it in the usual way (as in touching the contents).  That would be much
more conveniet than answering "no".  (Personally, I just have a "don't
touch my file" reflex that translates into C-g, then switch to the
open buffer, then revert it.)

Sounds similar to bug #10726.

Similar, but I don't think that it's the same bug.  In my case, I
really want the interactive version to avoid asking the question and
instead just show me a message about it; possibly with a `ding', maybe
even a non-macro-terminating one, which is what I hacked the function
to do in my own environment.  (In fact, that #10726 sounds like more
of a real bug, where this one is strictly a feature request.)

A nice way to resolve this would be to have a variable that can hold
`ask' to do the same as now, `nil' to do nothing, or a function that
will get called (making it possible to do more things like
automatically reverting the buffer).

I'd be happy to submit such a simple patch if it helps.

Makes sense to me, so I've added this to Emacs 28 under the name
'query-about-changed-file'.
