    write_pipe(): Discard stdout output
    
    Previously, meld would print any stdout output from a command executed
    via the write_pipe() function to the command line.  As an example:
      $ ./bin/meld ./
      (Double click on the git.py file in the meld GUI)
      patching file meld/vc/git.py
      (Double click on the _vc.py file in the meld GUI)
      patching file meld/vc/_vc.py
    
    The "patching file XYZ" output from the 'patch' command litters the
    terminal window used to execute meld and doesn't provide any useful
    information.
    
    This change discards the stdout output of a command executed via the
    write_pipe() function.  Note that stderr output will still be
    printed to the command line as it can be useful in diagnosing why
    a sub-command is having errors.
