run-tests: insist that if people use Python 3, they use 3.5.x

We depend on both stdlib functionality (difflib.diff_bytes) and
language behavior (bytes formatting) introduced in 3.5, so let's try
and prevent some useless bug reports before they happen.

import sys

globalvars = {}
lines = sys.stdin.readlines()
while lines:
    l = lines.pop(0)
    if l.startswith('SALT'):
        print(l[:-1])
    elif l.startswith('>>> '):
        snippet = l[4:]
        while lines and lines[0].startswith('... '):
            l = lines.pop(0)
            snippet += l[4:]
        c = compile(snippet, '<heredoc>', 'single')
        try:
            exec(c, globalvars)
        except Exception as inst:
            print(repr(inst))
