Make TextEdit word selection more natural.

QTextControl will only extend the selection to a word if the cursor is
directly over it which prevents the selection being extended if the
mouse is dragged up or down a to a shorter line of text making it
difficult to select multiple lines of text.  Just disable that
limitation when the TextEdit word selection is enabled.
