/var/isconf/lib/perl5/Isconf.pm

I'm trying to use ISconf3 on a linux box.  This is not the last
portability problem I've encountered, but I need to go home :-).

When Isconf.pm runs /var/isconf/conf/init.conf on a Linux box, some of
the environment variables can be reported as empty lists.  In my
instance, I had a couple:

GROUPS=()
DIRS=()

Isconf.pm confused those values with function definitions, and thought
it had come to the end of what it cared about.  So may I suggest:

                /IFS/ and next; # we know we don't need to import IFS,
and it's got a carriage return
                ($var,$value) = split /=/ or next;
                unless ($value) { next; }
!               $value =~ /\(\)/ and last; # we don't want function
definitions
                $value =~ s/^['"]//;
                $value =~ s/['"]$//;
                debug("$var is [$value]");
