always receive a LoginForm when opening tunnel

[GoogleCodeExporter]

What steps will reproduce the problem?
1. put the string "login" in /etc/motd on remote machine
2. create tunnel to remote machine


What is the expected output? What do you see instead?

ptm watches for "login" to appear in the ssh session, but a string in the 
remote motd can trigger a match.

What version of the product are you using? On what operating system?

p-t-m latest, win7


Please provide any additional information below.

Changing the search string from "login" to "login:" solves this for me, 
although it'll obviously be a little difficult to match that prompt 
reliably.
