I had posted it here before, but I've got around to formally put it
into a CF, so sorry for not cleaning up. The double-formatstr thing
was done to avoid the need for twice as much almost-identical
formatstrs. There's probably smarter ways to do that.

The patch tries to reuse the existing switches; --host=/tmp is just
the equivalent of the "host=/tmp" connection parameter. Of course it
could as well introduce a new parameter --socket-dir=/tmp.

The patch solves a usability problem, security wasn't a concern at the
time of writing. I'll rethink that bit and come up with a better
solution.
