Thanks to _any_options parameter, git.py can dispatch options to
sub-parsers correctly.

In order for sub-parsers' help to be triggered correctly the top-level
parser's help was implemented manually (help=False), otherwise -h|--help
would always trigger top-level parser's help even when invoked as
`subcommand -h`. This is a bit unfortunate.
