And of course I forgot to provide the footnote. Sigh. So here they are,
the Git garden shears, intended to rebase a thicket of branches:

https://github.com/git-for-windows/build-extra/blob/master/shears.sh

The edit script will look somewhat like this:

	mark onto

	# branch "something"
	bud
	pick abcdef first commit
	pick abcde0 second commit
	mark something

	# branch "another-one"
	bud
	pick cafebabe yep, that's a different branch
	mark another-one

	bud
	merge -C 0123456 something
	merge -C 6543210 another-one

	cleanup something another-one

So you see, I needed to introduce new commands: bud, mark, merge and
cleanup (I actually also added a "reset" one).

The fake editor I talked about is really the script itself, which detects
that it was run as the fake editor, and which converts all those commands
into the form "exec git .r <command> <parameters>...". The alias..r
setting also points to the same script, so that I really only need one
script. It's one big hack, but it works.

Needless to say, my idea to support new rebase -i commands via config
settings would be something I would use myself in the Git garden shears.

Ciao,
Johannes
