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
