I like the idea of .files returning an array of just filenames. Great idea!

But, if .files is implemented, what should .value return then? Always
just the first filename? A separated list of platform-dependent
filenames with a separator that makes sense for separating filenames
on that platform? Nothing?

On a side, I'd like .paths to return a list of file URIs (when I allow
it, like for local pages or specific sites).  Be nice for building a
playlist for scripting media player type plugins or even Audio and
Video. That way, you could choose a bunch of files in a different
directory than the page and have the paths load in a playlist. (Or,
even use a script to convert the file URI to a platform path if the
plugin doesn't understand file URIs). Of course, I guess that'd have
to be a browser-specific thing and .vendor_paths.

Anyway, .files returning an array would be a lot better than trying to
parse some platform-specific separated list string that .value might
