[docs] [issue16380] true/proper subset

[abcdef]

New submission from abcdef:

The documentation

http://docs.python.org/2.7/library/stdtypes.html#set-types-set-frozenset

http://docs.python.org/3/library/stdtypes.html#set-types-set-frozenset

of "<" for sets uses "true subset" and "true superset". The correct termininology is "proper subset" and "proper superset", as evidenced by Google searches

http://google.com/search?q="true subset"

http://google.com/search?q="proper subset"

and most set theory books.
