[Novices] very simple at commands

Right, I was thinking about how the environment ($DISPLAY) doesn't get
passed to at/cron jobs.  Even $PATH is not passed.

What I wasn't sure about is if X authentication would be a problem.
But I guess as long as as the same user is logged on as started the
at-job, ~/.Xauthority should be readable and it should work.

As long as the same user-id is logged in, it should work (in theory).
It wouldn't be difficult to test if anyone cares.  (which I don't :)
