rebase -i: demonstrate a bug with --autosquash

Browse Source 
When rearranging the edit script, we happily mistake the comment
character for a command, and the command for a SHA-1. As a consequence,
when we move fixup! and squash! commits, our logic to skip lines with
already handled SHA-1s mistakenly skips anything but the first
commented-out pick line, too.

The upcoming rebase--helper patches will address this bug, therefore we
do not need to make the current autosquash code even more complex than
it already is, just to fix this bug.
