This turns out not to be a bug, but simply a different (and, it turns
out, a much improved) interface for the same purposes. I apologize for
the haste (also, I could not find a way to simply rescind it).

Status: Incomplete => Invalid

Public bug reported:
Up to rel 17.04, we were able to choose the mode for a second display as
either "mirrored" or "extended". With rel 17.10, it always defaults to
"extended".
