I favor starting with a dot as it's nothing the user should fiddle with ;)

Alright, i just tested it out by sharing several repos and pushing to one of
them, then fetching all again. Behavior seems as expected, so the remotes and
their branches shown are isolated correctly.
Plus the initial fetching is quite a lot faster, less disk space used, etc…
So i think this is the way to go, thanks for the nudge.

I'll prepare a v2 of the patch.
