3 things

IMO, there are three things I'd like to get agreement on in Sapporo and
then I'll be happy encouraging our Chrome editing folks to consider
implementing what we've got.

1. The composition + focus change thread I just sent an email about.
2. Spec the delete behavior. I think this is a small subset of execCommand
and is the only way to make contentEditable=typing not treat IMEs in some
weird, special way.
3. As complete a list as we can get of the editing types.

FWIW, we can implement each of these 3 independently, so they don't block
each other.
