Allow specification of argument documentation for flags

If all three documentation strings are specified for a bool option,
then the usage, html, and man documentation will include the argument
documentation (first string), just like for non-flag options. This is
primarily useful for using options to handle commands where you may
want to end up with something like "help [<options>] <command>".
