I forgot to mention it in the patch, but let me know if others would
prefer _vc.popen(), subprocess.Popen(), or something else over
os.system().

Also, is it preferred to "hide" all subprocesses output so that
nothing is printed when meld is ran from the command line?  Eg right
now I see the following:
$ ./bin/meld ./
(I click on the git.py file in the meld GUI)
patching file meld/vc/git.py
(I click on the _vc.py file in the meld GUI)
patching file meld/vc/_vc.py

Is the "patching file xyz" command line output intentional, a bug, or
just some output no one cares about either way?  My os.system() call
in this patch adds some additional output is why I ask.

Thanks,
Peter
