This sequence was terse, to the point and very readable when the
logic was simpler, but now it is getting out of hand.  I think
it is a time for rewriting to something more verbose, like...

	# Decide the directory name of the new repository
        if test -n "$2"
        then
        	dir="$2"
	else
        	# Derive one from the repository name
                if test -f "$repo"
                then
                        # Cloning from a bundle
                        dir=... humanish ...
                else
                        dir=... humanish ...
                fi
        fi
