Reviewed by Ryosuke Niwa.

This patch is to fix three regressions stemming from 257136@main.

1) Breaking chat window or login forms while trying to press 'space' key.
2) Add nbsp instead of plain space between text nodes in case next text node 
has a leading plain space.
3) Not accounting for all kind of whitespaces including "Enter"
