Provide a way to comment commits other than at branch head

[linquize]

For example: refs/heads/feature -> 0123456789012345678901234567890123456789
parent commit 01234567890123456789012345678901234567AB
parent commit 01234567890123456789012345678901234567CD
parent commit (refs/heads/master) -> 01234567890123456789012345678901234567EF

I can only comment on 0123456789012345678901234567890123456789.
I need to also comment on 01234567890123456789012345678901234567CD

Yes, that should be a supported feature. We could either add a new flag to the comment command, or maybe provide some sort of interactive mode for writing comments.
