The error message is being spat out by getopt, which is used by the
platform API to augment the applications’ capabilities with command-line
switches such as --form_factor_hint or --desktop_file_hint.

It can be suppressed by passing an extra "--" between the platform-specific
options, and the application-specific options, like so:

    webapp-container --desktop_file_hint=… -- --enable-back-forward
--webappUrlPatterns=… URL

Either way, with or without this extra "--", the application specific
options are recognized and taken into account, so really, there’s no need
to worry about this warning.

A bug report at https://bugs.launchpad.net/platform-api/+filebug would be
useful to improve the usage message to include application-specific options
(see print_help_and_exit() function in
http://bazaar.launchpad.net/~phablet-team/platform-api/trunk/view/head:/src/ubuntu/application/common/mircommon/application_options_mir.cpp#L69
).

As far as I can remember, this warning was already present in trusty, so
that’s not a regression.
