I used the recommended gnulib driver:
[merge "merge-changelog"]
name = GNU-style ChangeLog merge driver
driver = /usr/local/bin/git-merge-changelog %O %A %B

I don't think Git merges can work that way, though. They bring in the
whole branch, you can't exclude some commits. You have to either
cherry-pick the ones you want instead of merging, or revert the ones you
don't want after merging.

You do it to the two branches that were merged. So e.g.
commit ba4502fe1465f7803beca3ae187e41f0b25bef10
Merge: b121ef1 81e0cca
Author: Ted Zlatanov <address@hidden>
Date: Wed Nov 26 21:31:11 2014 -0500
Merge branch 'emacs-24'
means you do `git log b121ef1..81e0cca'

I can't believe I did that. Sorry. It's not harmful, but I was
careless. I've now added this alias to my gitconfig:
[alias]
pull-all = !"old=$(git rev-parse --abbrev-ref HEAD) ; for b in $(git
for-each-ref refs/heads --format='%(refname)') ; do git checkout
${b#refs/heads/} ; git pull --ff-only ; done; git checkout ${old}"
I can revert my merge commit for the reasons Andreas and Glenn listed,
or it can be patched up. Reverting is probably better to keep the
ChangeLogs clean. Let me know, or go ahead and revert directly (it will
have a few conflicts, nothing too bad).
