The first wouldn't, because 'M-w' is not 'kill-region', and for the
second, one would have to _move out_ of the form field (where the 'C-w'
happened) before pressing 'w'.

But indeed, when I came up with this I hadn't thought of the situation
where 'w' is rebound to a key-chord, perhaps, so that it could be typed
immediately after, in the latter case above. So the question now is
whether it's even desirable in such a (IMO, rare) case. If so, here's an
updated patch with a News entry.
