Joseph Huttner:
The bottom line is that good commit messages are really important, so
we should make it as easy as possible for developers to go ahead and
write a perfect commit message every time they commit code.
I recently started to work with the code review system Gerrit[1]. First I did
not pay attention to it, but later I was amazed that the commit message can
(and should) be reviewed just like the code changes.
So if you're using a code review prozess (you should!) then also include the
commit message in the review.
