is there some way to know how far you are within a rebase when the
rebase is interupted by a conflict other than the message given by
git rebase when it was interrupted ?
I do not think there is a "git $anything" command to do that, but in
the meantime you could "cat .git/rebase-*/git-rebase-todo" or
something.
Recent trend is to teach "git status" more about these internal states,
so with time the command may learn to include this in its output.
