I'm sorry! But you're a tough guy, you'll recover...

No, of course, I just added doc+test to your patch v2, since you seemed
to encourage people to do so.

I would have sent it out yesterday if my tests hadn't shown a problem.
(Or did you misunderstand my doc notation? <branch> = ${branch} =
"branch" placeholder for a generic branch name)

If I'm not totally off-track (which I may well be) then that problem
should show up with other uses of the merge/track setting as well. I
guess it's just that everyone tracks remote branches, not local ones.

I'll see if I have time...
