In the question that you sent to the list ;-)
(But something like s/\./?/ makes more sense.)

The real answer of Johannes to your question was only:
> You might be happy with a post-merge hook amending the commit with a
> completely different message.

Meaning, you should put something like
 #!/bin/sh
 git commit -m "This is my new commit message." --amend
or better:
 #!/bin/sh
 git commit --amend -m "$(git cat-file commit HEAD |
 	sed -e '1,/^$/d;s/^/YOUR SIMPLE STATIC STRING HERE\n\n/')"
into .git/hooks/post-merge (and make it executable).
YOUR SIMPLE STATIC STRING HERE is the new first line.
Replace the \n\n by a space to get someting like
"YOUR SIMPLE STATIC STRING HERE Merge foo into HEAD."

Let the commit-msg hook add the text afterwards.

Or remove the prepared commit message in vi and then press :x (or :wq),
because commit aborts on an *empty* commit message and not on 
an unchanged commit message.
