The functions in getgrent.c don't work right, because gr_mem isn't set
up properly to deal with emtpy groups or the end-of-line. The return
value from strsep() is the buffer pointer given to strsep()
The functions in getgrent.c don't work right, because gr_mem isn't set
up properly to deal with emtpy groups or the end-of-line. The return
value from strsep() is the buffer pointer given to strsep() so there's
an extra blnak entry at the end of the user list. The field can be zero
length if there are extra space.
