I've updated the proposal per discussions so far.  I've kept apply, unapply,
& reapply attributes and made reapply optional:

I'm going to keep those names for now since none of us have come up with a
better name yet.  For what's worth, those are exact names WebKit's
EditCommand<http://trac.webkit.org/browser/trunk/Source/WebCore/editing/EditCommand.h>uses.
