Slight semantics change: ALWAYS use YP if the system is bound to a

YP server.  This is required if the passwd database is to stay in sync
if this program is run on the YP server.  Note, local passwd database
operations can still be performed by passing the -l flag.

Also, some minor cleanup and RCS id police.
