IIRC it was you, Junio, who complained first that the local branches have tracking set up.

The point here was to find out what to track when we do a "git branch --track <name> <origname>". So we definitely only want to find those remotes that fetch to a certain tracking branch.

Sure, you can set up branch.<x>.merge to a branch that is not tracked. But git cannot find out which one it is in the command "branch".

Dude, I, uh, I think I, uh, don't remember.  Peace.

Ciao, Dscho
