This version looks pretty good to me (though I do have a few comments
below), and now that we are in the new release cycle, I think it is time
to re-submit "for real".
The big question is what is happening with the recount work. Johannes,
are you planning on re-submitting those patches?

Yeah, thinking about it more, that is the sanest choice.

I would leave it; it seems like the editor's responsibility to handle
this. We don't know what patterns are used, or when it is safe to remove
such backups. And this is far from the only place where we invoke the
editor on a temporary file, so any solution should probably be applied
globally.

Reading over this again, I wonder if it should be:
# Abort if nothing remains
if (!grep { /\S/ } @newtext) {
return undef;
}
That is, we can't eliminate blank lines on input, since they might be
meaningful to the diff. But if the user removes every non-comment line
_except_ a blank line or a line with only whitespace, we probably want
to abort, too.
