The '[no]' formatting is similar to how some (but not all) man pages do
this. If it is too difficult, I'm open to something else. Just a note
somewhere that all boolean options have equivalent '--no<foo>' options?

BTW, one thing I didn't note in the commit message is that this is
important because some options are already *on* by default, and so it is
only sensible to use the --no version, which isn't even documented.
Particularly, options like --norolestats.
