fix odd version comparisons (#988)

"> (3,)" works but looks like the code is checking for Python 4.

"<= (3, 5)" was intended to check for versions up to and including 3.5, and probably works that
way in current type checkers. However, sys.version_info is actually a 5-tuple that is greater
than (3, 5), so a hypothetical type checker that uses the full version info would interpret
this check incorrectly.

This ensures that all version_info comparisons use <, >=, ==, or !=.
