Hi,

I like the patch.  Just a couple comments:

Here, "-i" is not an error, but not required either, so it should be

+git-rebase [-i] (--continue | --abort | --skip)

I wonder if these options (which really should be subcommands) should not 
go below the options, for chronological reasons: you are likely to need 
the other options before --continue and friends.

Hmm?

You probably need to introduce checks against "git rebase --continue 
--onto blabla", then.

I consider this a bugfix.  Thanks.

This exit is not really necessary, is it?  Besides, a simple "exit" would 
be more correct: it reuses the exit status of the most recently executed 
command, which is what we want here.
