First let me state that I really don't know the proper place to be
putting this.  If this is the wrong list, I appologize, please let
me know the prefered method for submitting minor patches.  It seemed
that send-pr was just for reporting issues, not for fixing them also,
if this should've gone through send-pr....well...oops :P

this is just a fix for this:

a common way to look for pids
ps aux | grep myps

but even though stdout isn't a tty ps tries to use 79 col, and I
don't like typeing ps wwaux | grep myps.

so this patch just checks if stdout is a tty, if not it defaults to
UNLIMITED.
