thanks for the info! here are my results on a 2.2.0-R system:
$ f ; echo $?
78
$ g ; echo $?
0 <-- this one is not correct as you describe
$ h ; echo $?
78
$ exit
if this truely be a bug, what should happen next? as i mention below,
i've worked around the problem. i suppose someone should take steps to
make it right. i'll gladly file a bug if someone will clue me in on the
correct procedure.
thanks,
-scotto
