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.

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).
