  Log Message:
  -----------
  There's no Python 3.8 on Appveyor

https://www.appveyor.com/docs/windows-images-software/#python does not
list Python 3.8 as an available version.

(In fact Python 3.8 is not out yet.)

Having it listed in appveyor.yml confuses tools like my
check-python-versions, as they detect an inconsistency between supported
Python versions listed in appveyor.yml with those listed eg. in
setup.py.
