Support inline style with --fallback-style parameter

Please excuse me if this is not the preferred way of posting a feature request.

Would it be possible and sensible to have the command line option --fallback-style not only accept default styles, but also advanced specifications like
{BasedOnStyle: WebKit, AlignTrailingComments: true'}?

The reason for this request is that it makes a better integration in editors possible, in this case for vim.
