    nvi - Work around problem with git
    
    * When a vi session managed by a git commit is ^Z'd and then resumed, git
      for some reason will set STDIN to O_NONBLOCKING.  Not only will it do
      this, but the git process will do it in parallel with the resume so
      the point at which stdin becomes non-blocking from the point of view
      of vi is completely non-determinisitc.
    
    * Do an end-run around badly behaving parent processes by using extpread()
      to explicitly override the blocking/non-blocking mode.  Now nvi doesn't
      care whether stdin is in non-blocking mode or not.
