tramp ($Id: tramp.el,v 1.436 2000/12/15 23:36:40 grossjoh Exp $); only telnet methods work

[Mark A. Hershberger]

--bug report follows this line--

I've tried tu, su, sudu, multiu/telnet/sudo and of all these
connection methods, only tu seems to work.  This is a new (to me)
machine, so it is possible that I'm doing something wacky.

Here is the output after toggle-debug-on-error for one of the failing
methods:
