+## Incidental motivation
+
+This reflection started because moving over this underlined space with
+`truncate-lines` on caused the screen to jump horizontally.  This
+specific problem was fixed without dragging FORM FEED display into the
+discussion, but I feel like the latter is the more interesting issue
+([who on Earth] enables `truncate-lines` by default anyway).
+
+Also `page-break-lines` breaks down in a couple of scenarios
+(e.g. form feeds embedded in diffs shown in Gnus or Magit; somehow
+vc-diff seems to fare better).  Those could probably be fixed, but it
+feels like effort would be better spent improving core, for the
+reasons given above.
