OK, your choice. My choice will be the MP implementation of the straight
segments with control points overlapped with nodes. ;-)
More seriously, I agree that a flag is a useful and reasonable
implementational trick. Still, for further processing of the
output, it is nice to have "genuine straight" line segments,
distinguishable from a plethora of weird pseudo-straight lines...
(e.g., such that look as they were straight lines but acually are loops).
