[issue13238] Add shell command helpers to subprocess module

There's also https://pypi.python.org/pypi/sarge

One other thing I *often* want to do when scripting commands is to capture output, but provide some form of "progress" reporting (something like a dot per line of output, usually). That's annoyingly verbose with subprocess.
