Comment (by ryandesign@…):

 Yes I've noticed some ports needing to go to unusual lengths when the
 github portgroup is used in a subport but not in the main port. I did not
 anticipate this usage pattern when creating the portgroup.

 I'm open to a change to the portgroup that would set name only if it isn't
 already set.

 Perhaps the bitbucket portgroup (which was based on the github portgroup)
 needs a similar change.
