Comment 4 for bug 1244227

So the current behavior is this:

- With autocompletion off:
tapping on a word in the word ribbon will also add a space

- With autocompletion on:
pressing the space bar will insert the first word in the ribbon and insert a space

What I think needs to be fixed:
1) when you manually type an end of sentence punctation (".", "?", "!") we should remove any leading space in front of it.
2) with autocompletion on, double tapping the space bar should insert the first word in the ribbon (as it does now) and add a "." and space.
