[bug-inetutils] Incomplete usage info for telnetd

[Mats Erik Andersson]

Hello,

the Texinfo page for Telnetd is seriously lacking essential
information. Let me propose the following additions. They
have been compiled from the source 'telnetd/telnetd.c'.

The little experience I have in writing Texinfo source,
only lead me to use '@samp{}' repeatedly to accomplish
the mark up.


Best regards,

Mats E A
