[9fans] telnet

["boyd, rounin" <boyd@insultant.net>]

it seems that telnet has departed from the man page and the
utility of using it (albiet not strictly correctly) with smtp, pop,
ftp etc ... has also been lost.

here is a diff so you can:

    telnet host

    telnet host!service

service can be textual or numeric.

as far as i can see 'net' [see netmkaddr] will always be 'tcp'.

all done with drawterm [to NY], mousepad and 2 buttons.

i have not hacked the man page into shape.
