Weird failure of a merge to local branch

Fine by me.

A fine point of usage: to me, "mirror" implies "automatically" and/or
"should not get out of sync", while sync is more flexible.
Specifically, sync with a --bidirectional option as suggested by Marco
would support the "poor man's bound branch" workflow, but I wouldn't
expect that from "mirror".
