Cron and at behavior in X

[ke6isf <ke6isf@chez-vrolet.net>]

Using Sarge, current updates.

Based on conversations I've had on the IRC channel, I know that entering a
line into crontab such as 'x-app:0.0' will fire off an X application
without returning an error that it can't find a display, or similarly if I
set DISPLAY=:0.0 at the top of the crontab.  Am I correct then in assuming
that this behavior will be the same if I do something similar for an at
job?
