Subject: 28.0.50; `diff-no-select': no documentation for BUF argument
Date: Thu, 10 Sep 2020 15:40:37 +0200

The signature for `diff-no-select' is:

(diff-no-select OLD NEW &optional SWITCHES NO-ASYNC BUF)

Its docstring refers to `diff' for the meaning of the arguments, but
`diff' doesn't take an argument, so BUF is undocumented.

Probably `diff-no-select' should also document that the return value is
BUF if BUF is non-nil.

I've now amended the doc string of the function on Emacs 28.

Thanks, but please backport this to the release branch, as doc changes
should be installed there.

Also, the new doc string of diff-no-select uses too much of passive
tense; can we improve that?

And finally, the SWITCHES argument is left semi-documented, since the
doc string of 'diff' doesn't tell what happens in non-interactive
calls if SWITCHES is specified, and doesn't say what should be its
form in that case.

I've taken a what of it.

I've now removed the punting to diff and just explained the options in
this doc string.

If the final result now looks OK, I can backport it.  It didn't seem
important enough (it's an internal function) to me, though.

Thanks, LGTM.  Although I would add that SWITCHES should be a list of
command-line switches.

And yes, let's backport this to the release branch.  I agree that this
is not very important, but backporting is easy.

Yup; I've now added that bit about SWITCHES and copied to emacs-27.
