    Cygwin: pty: Fix a bug on redirecting something to /dev/pty*.
    
    - After commit 0365031ce1347600d854a23f30f1355745a1765c, key input
      becomes not working by following steps.
       1) Start cmd.exe in mintty.
       2) Open another mintty.
       3) Execute "echo AAA > /dev/pty*" (pty* is the pty opened in 1.)
      This patch fixes the issue.
