commit 77247c077b3334dc987d3f7269d42b75807abcf3

    Cygwin: pty: Discard input in from_master_nat pipe on signal as well.
    - Currently, pty discards input only in from_master pipe on signal.
      Due to this, if pty is started without pseudo console support and
      start a non-cygwin process from cmd.exe, type adhead input is not
      discarded on signals such as Ctrl-C. This patch fixes the issue.
