Bug#2109: netstd: rwhod manpage has error

[Austin Donnelly <and1000@cam.ac.uk>]

Package: netstd
Version: 1.23-1

rwhod(8) says:

:
:     The server transmits and receives messages at the port indicated in the
:     ``rwho'' service specification; see services(5).  The messages sent and
:     received, are of the form:
:

however, this is wrong: the port number rwhod uses is that given in
/etc/services by the 'who' entry (513, udp), not 'rwho'.
