happens for short words following the attempts to improve #86
now the auto-correct should only happen if suggestion has already been used in this ngram context,
and should not appear again quickly after correcting back to the typed word
e.g. type "whem" and space, autocorrected tho "when"
press delete and get "whem" again
select "when" suggestion (or any other)
get " when" instead of "when"
