 Well, that might imply/be interpreted by a lot of people that "--set" and
 "--list" are optional.  If we go that route, then maybe some additional
 logic should be in place that basically states:

  * if they give only `port select something`, then treat it like a list
 command
  * if they give `port select something valid-selection`, then treat it
 like a set command
  * if they give `port select something invalid-selection`, then show an
 error stating as such and give them the list of valid picks.
