I'm starting to think option 6 (storing cover latter as an empty
commit at tip then git-merge replaces it with a merge commit in a
permanent history) may be the way to go. It handles detached heads
just fine, we have reflog to store older cover letters. Though it will
not play nice with 'git commit --amend' and 'git reset' for people who
rewrites history heavily during development, but maybe 'git rebase -i
--autosquash' would be an ok workflow alternative.
