these modern terminals both compose a nicer title if we don't try to provide a custom one (no path in title twice, "fish" in title twice) - and the user can configure which components they'd like in their terminal inside the terminal preferences. Also make test "$VTE_VERSION" -ge .. work once I commit `test` strtoi fix - the trick is to add a zero before it so the numeric comparison works even if it's empty. Fixes #107
