The logic to move the lines seem to have been improved since the last
round, which is good.  I've amended this to remove "$1.rearranged" as well.

Unlike the very initial round, but like the second round, this feature is
controlled by an explicit command line option, so it should be reasonably
safe.

I hate bikeshedding but somehow

    git commit -m "fixup! commit with this message"

feels much more natural than having to write

    git commit -m "!fixup commit with this message".
