        summary:     (4) merge two known; one immediate left, one immediate right
   
-Draw only part of a grandparent line differently with "<N><char>"; only the
-last N lines (for positive N) or everything but the first N lines (for
-negative N) along the current node use the style, the rest of the edge uses
-the parent edge styling.
+Previously, one could specify graphstyle.grandparent = <N><char> to draw <char>
+on only the last N lines (for positive N) or everything but the first N lines
+(for negative N), with the rest of the edge using the parent edge styling.
 
-Last 3 lines:
+This was removed, and this test now shows that muliple characters being
+specified in graphstyle.grandparent aren't treated specially (including in width
+calculations; there's no specific reason to *avoid* handling the width
+calculations, but it's difficult to do correctly and efficiently).
