>Description:

innetgr seems to be broken in 2.2.5-RELEASE.

I just upgraded from 2.2.1-RELEASE where netgroups worked fine, and now lookups  
don't work properly.   When a host belongs to more than one netgroup, innetgr  
seems to ignore the one listed last.


>How-To-Repeat:
Set up a netgroup map using a netgroup file like:
allhosts (good,,) (bad,,)
zallhosts (good,,) (bad,,)
badhosts (bad,,)

% ypcat -k netgroup.byhost
good.* allhosts,zallhosts
bad.* allhosts,badhosts,zallhosts

The output of the following program:
#include <stdio.h>
void main( int argc, char *argv[] )
{    printf("innetgr(%s,%s,NULL,NULL)   ->  %d\n", 
        argv[1], argv[2],innetgr(argv[1], argv[2], NULL, NULL ) ); }

Gives:
innetgr(allhosts,good,NULL,NULL)   ->  1
innetgr(allhosts,bad,NULL,NULL)   ->  1
innetgr(badhosts,good,NULL,NULL)   ->  0
innetgr(badhosts,bad,NULL,NULL)   ->  1
innetgr(zallhosts,good,NULL,NULL)   ->  0
innetgr(zallhosts,bad,NULL,NULL)   ->  0

The last two tests are incorrect.
