My first cut at your feature request didn't go so well; it's tough for
two reasons:

1) the *vc* buffer is used both for 'C-x v l' and also when you do
   'C-x v v' to commit a file, so it might contain either info that
   your commit was successful, or the actual log info...would it be OK
   to change 'C-x v l' to write to something other than the *vc*
   buffer, say the *vc-commit-history* buffer?

2) cache coherency problem.  What if the log info is updated b/c of
   new commits?  Do you always want the outdated log info?

Any comments on these issues?  Thanks,
