This is a followup to a thread with subject "[PATCH] doc: Various fixes to
makedocbook for python3.8" that began on the newlib list and then moved to
https://cygwin.com/pipermail/cygwin-apps/2020-August/040442.html,
where it evolved into a discussion of moving from python2 to python3. A recent
post on the cygwin list reminded me that we never finished that discussion. We
left it with the question of what to do about scripts with a shebang that names
python but might not work with python3.
With python2 reaching EOL in a month, it seems that we ought to finish that
discussion and make the move.
