telnetd doesn't provide REMOTEHOST environment variable?

[glhs329 at gmail.com]

My application wants/needs to know the address of the host that's
connected via telnet, but the REMOTEHOST variable doesn't seem to be
provided. Was this an active decision? Oversight? On the TODO list?

I've written a patch that works for my situation. Is this something
the group might be interested in? If it is of interest, should it be a
configurable option?
