    Cygwin: console: Correct the past fix for apps which open pty.
    
    - The commit "Cygwin: console: Fix issues of apps which open pty."
      did not fix the second problem correctly. That commit looked to
      fix the issue, but the actual problem was that ctrl_c_handler()
      should be reregistered *AFTER* FreeConsole()/AttachConsole().
      This patch correct that.
