[bug-gawk] Typo in group.awk

[Jaromir Obr]

Hi,

I've hit a typo in group.awk causing that getgruser() doesn't work well for member of more groups :

_gr_groupsbyuser[a[i]] = gr_groupsbyuser[a[i]] " " $1

There is missing "_". The correct assignment should be:

_gr_groupsbyuser[a[i]] = _gr_groupsbyuser[a[i]] " " $1

Best regards
