Ok, Bryan. I'm posting a draft version of my Chain macro and a short test
scene in binary.images, under subject "True catenary". Rather than
specifying the Streteched length, you specify a Slack factor, which is just
the string length divided by the direct distance between P1 & P2. It
calculates the SegmentCount itself (and segment length) itself.

Have a play with it, I'd love to hear any feedback & suggestions.
