Why, I think it could be quite simple. It is not about the line, but about word break. So, if word starts (and/or ends) with a syllable shorter than two letters, first two (or last respectively) would not be split up. Thus ”hyphenate” instead of ”hy-phe-na-te" would result in "hyphe-nate”, and ”hyphenated” would result in ”hyphe-na-ted”.

@veezh, please confirm if I understood it correctly. Quite a simple feature, I would add without a problem.
