LGTM, with optional suggestion.

Can I make one minor suggestion whilst you're changing these lines: Change the single-dash arguments for double-dash (or vice versa, but I prefer the first). The reason is that there's an inconsistency in the number of dashes for different options, and it would be nice if it were consistent. It's not a big deal at all of course!

Sure, but how do you prefer to write -vv?

Hmmm... good question! I'd probably do single dash, but don't mind either way.

OK, I'll go with -- for everything here but -v and -vv. Thanks.
