Only consumer is devel/py-argh. Which, sadly, doesn't have any tests
since we're missing needed libraries to test. py-argh only has one
consumer, databases/barman. It also, sadly, doesn't have any tests
because we're missing needed libraries.
The corrections look minor enough that I don't foresee a problem, but
if someone who uses py-argh or barman wants to try this out to be
extra sure, that would be great.
