I agree with Junio; setting -u in your interactive shell is as bad
as export CDPATH.  Its crazy.

These are orthogonal to the -u corrections.  They should be in a
different patch.  The comments are wecome.  The '#!bash' looks like
a good idea.  But a vim specific modeline, I don't like, for the
reasons Junio has already stated.

This is one of those places where [ -z "${1-}" ] is likely easier
to read then the || usage you have introduced.  We don't care if
we got no args, or we got one that is the empty string, either way
the $1 cannot be a gitdir and we need to guess it.

Eh, I'd rather see [ -n "${1-}" ] over the && test.

Why are we switching to bashdefault?  Is this an unrelated change
from the -u stuff and should go into its own commit, with its own
justification?
