I can understand how this "sign" command helps you. I myself wished for
new commands when working on my Git garden shears [*1*] (essentially, what
git rebase --interactive --preserve-merges *should* have been).

My solution was to introduce a new fake editor that calls the real editor
and afterwards converts the "new" commands into exec lines.

Having said that, this patch clashes seriously with my current effort to
move a lot of the interactive rebase from shell into plain C. It is
actually ready, but getting this into the code base is really slow-going,
unfortunately.

Now, after looking at your patch it looks to me as if this would be easily
ported, so there is not a big deal here.

However, I could imagine that we actually want this to be more extensible.
After all, all you are doing is to introduce a new rebase -i command that
does nothing else than shelling out to a command. Why not introduce a much
more flexible feature, where you add something like "rebase -i aliases"?

Maybe something like this:

[rebase "command"]
	sign = git commit --amend -s --no-post-rewrite --no-edit -S

I have not completely thought this through, but maybe this direction would
make the interactive rebase even more powerful?

Ciao,
Johannes
