[hacknews] nohup bug fixed

henry (09/22/82)

Fixed a minor bug (mishandling of PATH) in nohup(1).  Note that use
of nohup is the preferred way to run something in the background if
it is intended to keep running after you sign off.  Simply tacking
an & on the end is not guaranteed to make the process survive signoff
(it does now, but this is not guaranteed to continue forever).
