Neither specifies a repo, unless you count "the default dir on the
remote side" (do we support that?).  The existing code would have
snipped at the / and constructed something like ssh:/otherrepo.

These work fine because the first case arm is "do we still have a
slash?", and thus takes precedence over the colon splitting.

That's caught by the outer 'case':

		case "$url" in
		../*)
			url="${url#../}"
			# ... what we're discussing here
			;;
		./*)
			url="${url#./}"
			;;
		*)
			break;;
