[PATCH v3 3/4] get_maintainer: add --no-foo options to --help

[Brian Norris <computersforpeace@gmail.com>]

Many flag options are boolean and support both a positive and a negative
invocation from the command line. Some of these are even mentioned by
example (e.g., --nogit is mentioned as a default option), but they
aren't explicitly mentioned in the list of options. It happens that some
of these are pretty important, as they are default-on, and to turn them
off, you have to know about the --no-foo version.

Rather than clutter the whole help text with bracketed '--[no]foo',
let's just mention the general rule, a la 'man gcc'.
