All of the setter methods in Zend\Mime\Part and Zend\Mail\Message return $this, allowing you to chain calls to those methods. Zend\Mime\Message doesn't work this way, for seemingly no particular reason.
The PR simply adds return $this to those few setter functions. There should be no API breakage or other BC issues AFAIK. Tests pass (there weren't any that relied on the existing behaviour, of course).
