select_autoescape default value for default_for_string should be False

[clavedeluna]

According to jinja's select_autoescape documentation

The select_autoescape() function returns a function that works roughly like this:

def autoescape(template_name):
if template_name is None:
return False

Furthermore, the docs makes it clear that jinja's default autoescape is still False. So, If I setup autoescape like this:

from jinja2 import Environment, select_autoescape
env = Environment(autoescape=select_autoescape())

I would expect autoescape to end up as False

However, in the code here when template_name is None, it returns the default value of default_for_string, which at this time is True.

Should default_for_string not be False, just like default?

• Python version:
