Hi,
the following patch changes two files in the contrib/cygwin subdir:
It changes the Cygwin specific README file which adds some hints
related to the new feature to switch user context without password
(which means using public key and/or rhosts authentication). Some
old stuff is erased.
The changes to ssh-host-config are intended to allow an easier
startup for users which are new to Cygwin and/or OpenSSH.
