System: NetBSD beowulf.gw.com 1.5X NetBSD 1.5X (GW-GENERIC) #36: Sat Jul 28 11:41:19 EDT 2001 kim@nix.suominen.org:/net/nix/src-3/NetBSD/cvsroot/src/sys/arch/i386/compile/GW-GENERIC i386

>Description:
To denote an empty entry (no valid value) in a netgroup one uses
a hyphen "-" as the value.  However, getnetgrent returns this value
to the called as "-", which it shouldn't.
>How-To-Repeat:
Create a netgroup like this:

	test (-,-,)

Then use "netgroup test" and you'll see "-" returned.  This is even
worse when a group consist of multiple groups, some of which are
empty.  Multiple "-" entries will be returned.
>Fix:
The code in getnetgrent(3) should skip elements that are "-".
