patches/patch-??, which does not match e.g. patches/patch-aa~, which
will appear after updating patch comments, because I generally use
emacs. One can always explicitly remove the editor backups, but that's
a hassle, to some extent a risk of mistyping and removing everything,
and it's also not always advisable to do this before one has finished
If you're asking why this comes up, it's usually searching for
references to some identifier or other.

Basically the premise (of quilt or Mercurial's mq extension) is that
you get to keep a patch collection and then do mkpatches independently
for each patch. I'm not entirely sure what else you might mean by
"automated" but I *think* that covers it...

No, we don't, until someone makes a mistake (this happens from time to
time) or some end user hits a bug in patch (this too) and trying to
figure out what happened suddenly becomes impossible because it
depends on the user's setting of LC_COLLATE or whatnot that they
didn't report to us and possibly don't themselves understand.
Maybe this is a small risk.

It already does:

It does not do this without -Wall, so if what you're suggesting is to
turn this warning on by default rather than in -Wall, let's just do
