Reason (for both voteS): I have learned that the getoutput() and
getstatusoutput() functions in the commands module are exceedingly
popular amongst Googlers who write simple Python scripts that
occasionally invoke an external command. It's much simpler than using
os.popen() or the subprocess module (which is also very popular BTW).
But I have found no uses of commands.getstatus() in our entire
codebase so I'm okay with seeing that mistake finally eradicated (and
it was *my* mistake :-).
