title: cygwin ssh gives "Killed by signal 1" on exit
body: <p>After using cygwin's ssh to login from windows to linux-hosts, 
  when exiting the remote shell, I always get the annoying msg:</p>
  
  <p>"Killed by signal 1"</p>
  
  <p>I googled, and realize its harmless, but still annoying...
  Some suggested you can get rid of the message by using</p>
  
  <p>$ ssh -q ...</p>
  
  <p>But that has no effect on any of the machines I've tried.</p>
  
  <p>Anyone knows a working solution to get rid of this msg?</p>
