Is supplying all of the files to `scribble' at once an workable option?

In fact, there's such a prefix internally, but it's not currently
documented or exposed in the `scribble' command line. I can fix both of
those.

You'd end up with multiple copies of files like "scribble.css", though.
I'm not sure that's ok --- or how to avoid it, if not.
