[PATCH v3 1/9] help: correct the usage string in -h and documentation

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Clarify the usage string in the documentation so we group e.g. -i and
--info, and add the missing short options to the "-h" output.

The alignment of the second line is off now, but will be fixed with
another series of mine[1]. In the meantime let's just assume that fix
will make it in eventually for the purposes of this patch, if it's
misaligned for a bit it doesn't matter much.
