Sorry, I haven't got time to read my mails.  So you've found the answer, but
if it is true, it's a bug in /bin/sh.  The ``return'' command has to return
the status of the previous command, if return hasn't got a parameter.  So
try it:
$ sh
$ f()
return 78
$ g()
{
f
return
}
$ h()
{
f
}
$ f ; echo $?
78 # this is the correct answer
$ g ; echo $?
78 # this is the correct answer
$ h ; echo $?
78 # this is the correct answer
$ exit

If you got anything other than three 78's, send the bug report to
freebsd-bugs(?).

Bye, Gabor
