csih patch

[Corinna Vinschen <corinna-cygwin@cygwin.com>]

Hi Chuck,


I'm trying to make the ssh-host-config script more foolproof.  While
doing that I found a problem in cygwin-service-installation-helper.sh
which disallowed ssh-host-config to react differently if certain
problems showed up.

The csih_install_config returns a value which indicates if the
installation was successful.  However, it also returns 1 if the user
said "no" to the question if an existing config file should be
overwritten.  This is not correct, because it disallows the calling
script to check for a problem.  The "no" answer is not a problem, but a
deliberate decision, so it should be treated as if everything's all
right.

Here's a patch to fix that:

Thanks,
Corinna
