41C sunrise/sunset program listing: what are these strange "dot" steps?

All minus commands were turned into 0x95 (Windows-1252 bullet), while all other minuses were left alone (numbers, strings, HMS- commands). Maybe they were supposed to be rendered as 0x96 (en dash).

I was starting to wonder if it was some kind of text-encoding mishap. I tried all the supported encodings in Firefox, and none of them seem to change the bullet to a minus, so I can't imagine what happened there.

The 33S/35S programs on that page look fishy too. There are a bunch of occurrences of "1." that look like they're supposed to be a subtraction operation.
