Comment (by donmhico):

 Hey @pikamander2, I see your point. I supposed that if existing plugins /
 themes do want to use the default 55, they should have not passed anything
 as `$num_words` instead of passing empty string or null. And WP.org stays
 true to provide backward compatibility and not breaking any existing
 behaviour as much as possible.

 I'll upload an updated patch shortly.
