Nasty.   How did you achieve a negative compression ratio though?

I was a bit concerned about the cast to int in your patch, so I have
installed the patch below instead.

I periodically use "vc-update-change-log" in Emacs.  It automatically
generates the ChangeLog from the CVS checkin comments.  That means the
ChangeLog is always up to date in release tarballs, and at other times
might be or might not be up to date, and will often lag by a dozen or
so checkin comments.  Is this a significant problem?


Here's the patch:
