There is no point not removing the script if you update git.c
and Makefile to point at the new one.

We do not have a test specific for fmt-merge-msg, so it
obviously passes all the tests ;-).  A new one is attached.

I think we should extend boolean to accept 'yes' and 'no', as I
suggested earlier on the list, but other than that things look
good.

Thanks for the patch; no need to resubmit -- I'll munge the
points I raised above.
