Rather than using `set`, I, personally, would change this line to be:

    if [ -n "${XDG_RUNTIME_DIR:-}" ]

(as well as the matching check for $WAYLAND_DISPLAY).

Though this is just a matter of opinion, I think it is cleaner than
using `set`s (but only really because I have no idea what all the `set`s
do, without context).
