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"}.
