Please don't install my patch as is, as I realized it is not
necessarily a better solution.  In particular, to make kill and
yank work properly, we would have to improve the handling of
inlined editable input/textarea further.  Though I'm not sure
whether I can reach to the best result, I'd like to work on it.

Thanks.
