Cause: 'rhc ssh <app>' was not working in Windows, unless ssh.exe was copied from the C:\Program Files\Git\usr\bin folder to the C:\Program Files\Git\bin folder. Also the link to Git for Windows mysysgit install was broken.
Consequence: rhc was broken for Windows users
Fix: Added C:\Program Files\Git\usr\bin to the search path for ssh.exe. Users can also move ssh.exe to a custom location, as long as it is in the Git path rhc will find it. Also replaced 'http://msysgit.github.io/' with the updated url 'https://git-for-windows.github.io/'.
Result: 'rhc ssh' works as expected for Windows users
