As I said in reply to Takashi's mail I'm not convinced about all the
changes in here, a lot of it's really bikesheddy at the best of times
and to be honest there's more here that I don't like than do. The
changes aren't entirely consistent in the final style either so
presumably not great if there is any machine parsing going on. It'd be
much better to split this up into separate commits for separate changes,
that'd be a lot easier to review if nothing else.

I'm really unconvinced that replacing : with () is helping either people
or machines - the form we have at the minute is probably more common for
command line tools?

Why add the space before the : here? That really is not idiomatic for
Unix stuff, or just natural language.

This should definitely be a separate commit.

I don't understand the comma here?
