The custom help() is replaced by a COMMAND() description, and
--introspect-cli is added. The "Commands" option group is moved before the
other options and an explicit "Options" group is added, so that the sections
are printed in the same order as before. --help now goes through the pager,
like other commands with --no-pager. The mount.mstack helper interface is
described by a second COMMAND(), so that it is exposed by --introspect-cli
too.
