add-change-log-entry and vc

[Tom Tromey]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


Right now, add-change-log-entry will re-use an existing header if the
date and the author are both already correct.

It turns out that this isn't always the most useful approach.  In
bigger projects, I find it is clearer to have a separate entry for
each separate commit.  For one thing, this makes it simpler to merge
ChangeLogs in the case of cvs conflicts.

I think it would be useful if, when the buffer is unmodified,
add-change-log-entry would consult (vc-state) and only added a new
heading if the state is 'up-to-date or 'needs-patch.
