I like the idea but I think it would be better to only comment out the subject of the commit message if it starts with squash! for fixup! otherwise it may well be a useful part of the message. For correctness I think it would be better to comment out the subject (everything before the first blank line as returned by `git log --pretty=%s`) rather than just the first line. I've actually implemented this as part of a longer series that I've never got round to posting to the list[1] - feel free to use any of that which you find useful. That commit also shows an alternative way to change the --autosquash tests.
