baseset: drop custom __sub__ method
This add method is enforcing non-laziness, disabling multiple optimisations.
Benchmarks do not spot any significant difference but real usecase may. This
will also be important for further improvements to addset later in this series.
#require serve ssl
Proper https client requires the built-in ssl from Python 2.6.
Certificates created with:
printf '.\n.\n.\n.\n.\nlocalhost\nhg@localhost\n' | \
openssl req -newkey rsa:512 -keyout priv.pem -nodes -x509 -days 9000 -out pub.pem
Can be dumped with:
openssl x509 -in pub.pem -text
