Sometimes only expect positive values from cmdline so it's better
to filter at parsing cmdline step instead of validate later.

This aligns with our existing 'optional arguments' to 'options' change, and
seems more intuitive for users.

There's no need to iterate over the action groups here, as self._optionals and
self._positionals are available.

As an example, `recipetool create foo bar baz` shows `recipetool: error:
unrecognized arguments: bar baz` and then displays the main help, not the help
for the create command. Fix by saving the subparser name and using it in
parse_args() to look up the subparser.

This aligns our subclassed error() with that in the original class, using
_print_message and self.prog. Also add a docstring based on the original.

Naming these as "optional arguments" is perhaps slightly confusing since
some of the positional arguments might also be optional; in addition
it's rare (though possible) for options to be mandatory - up until
recently we had a recipetool option (-o) that was mandatory. It's not
perfect, but change it to "options" so it's at least a bit more
appropriate.

The listing of subcommands in the --help output for devtool was starting
to get difficult to follow, with commands appearing in no particular
order (due to some being in separate modules and the order of those
modules being parsed). Logically grouping the subcommands as well as
being able to exercise some control over the order of the subcommands
and groups would help, if we do so without losing the dynamic nature of
the list (i.e. that it comes from the plugins). Argparse provides no
built-in way to handle this and really, really makes it a pain to add,
but with some subclassing and hacking it's now possible, and can be
extended by any plugin as desired.
To put a subcommand into a group, all you need to do is specify a group=
parameter in the call to subparsers.add_parser(). you can also specify
an order= parameter to make the subcommand sort higher or lower in the
list (higher order numbers appear first, so use negative numbers to
force items to the end if that's what you want). To add a new group, use
subparsers.add_subparser_group(), supplying the name, description and
optionally an order number for the group itself (again, higher numbers
appear first).

Having to specify -f is a little bit ugly when a URI is distinctive
enough to recognise amongst the other positional parameters, so take it
as an optional positional parameter. -f/--fetch is still supported, but
deprecated.

Python's argparse module can't handle when several optional positional
arguments (set with nargs='?') are intermixed with other options. If the
positional arguments aren't optional then this isn't an issue; thus when
changing positional arguments to optional (as we are doing with devtool)
we need this workaround.
This is a pretty horrible hack, but we don't want this flexibility of
ordering to disappear simply because we made some arguments optional.
Unfortunately the corresponding bug remains unresolved upstream even in
Python 3, and argparse is not really designed to be subclassed so it
doesn't make things like this easy.

For scripts that use Python's standard argparse module to parse
command-line arguments, create a subclass which will show the usage
the usage information when a command-line parsing error occurs. The most
common case would be when the script is run with no arguments; at least
then the user immediately gets to see what arguments they might need to
pass instead of just an error message.
