Oops, sorry folks.  I've re-uploaded the patch to the master FTP server, 
and it should propagate to others soon.

That's right.  For 5.x, it is fairly straightforward:

    # cd /usr/src
    # patch < /path/to/patch
    # cd /usr/src/lib/libtelnet
    # make obj && make depend && make
    # cd /usr/src/usr.bin/telnet
    # make obj && make depend && make && make install

But 4.x has no less than four possible telnet clients that might be 
installed depending upon local settings of NOCRYPT, MAKE_KERBEROS4, 
MAKE_KERBEROS5, and probably others :-/
