shell32/autocomplete: Don't autocomplete at all on most control characters. 

Most control characters sent via some CTRL+key combination should not
autocomplete at all. ^C is one example, where just copying some text should
not show the auto-suggestion box (if not visible). ^V is another example,
where it is already handled in WM_PASTE, so it has to be a no-op here,
else auto-append from WM_PASTE would complete the text and then the ^V
autocompletion would remove every other suggestion in the listbox.
