Excellent!  This feature has been requested a number of times over the
past years (though nobody bothered to write a bug report before Ivan
helped out) and I'd strongly vote for including it in Emacs 24.1.

There's just one detail missing: A number of people asked for
highlighting _only_ the selected window and if a buffer appears in more
than one window the present mechanism won't help in this regard.  So
couldn't we have the mechanism also respect a window parameter
specifying some face as default window face with higher priority than
the face specified for the buffer?

Thanks for getting us this far, martin
