Return NULL for wildcard values in getnetgrent from nscd (BZ #16759)
getnetgrent is supposed to return NULL for values that are wildcards in the (host, user, domain) triplet. This works correctly with nscd disabled, but with it enabled, it returns a blank ("") instead of a NULL. This is easily seen with the output of `getent netgroup foonet` for a netgroup foonet defined as follows in /etc/netgroup: foonet (,foo,) The output with nscd disabled is: foonet ( ,foo,) while with nscd enabled, it is: foonet (,foo,) The extra space with nscd disabled is due to the fact that `getent netgroup` adds it if the return value from getnetgrent is NULL for either host or user.
