ack.  Anyway xwayland support means the default config is able to
start xterm.  I personally don't need much more than xterm and
firefox. :)

I had forgotten about this noop default.  I took the script from
wayland/sway/files so free commit for you!

Nope, I just copied the script and missed that line.  Fixed, though I
have no idea whether it matters or not.

Right now login(1) doesn't set XDG_RUNTIME_DIR any more and
LOGIN_SETXDGENV has to be passed explicitely to setusercontext(3).
So I think it's better to keep this failsafe value for now.

I have a diff pending for login(1) btw, but it received no reply so
far.
