For git-fetch it does not matter as I do not think there is any
valid case to pass an empty string as a parameter to it (even
"fetch from our own repository" requires a single dot).  But
from discipline point of view, I am not happy about this.

If you are talking about shell scripts, the standard way to do
that is to say ${1+"$1"}.
