Specify that SSLContext.set_default_verify_paths is called on ALL systems.
The code of SSLContext.load_default_certs was changed in bpo-22449 to do this,
this fix corrects the documentation to match that change.
Load a set of default "certification authority" (CA) certificates from
default locations. On Windows it loads CA certs from the ``CA`` and
- ``ROOT`` system stores. On other systems it calls
+ ``ROOT`` system stores. On all systems it calls
:meth:`SSLContext.set_default_verify_paths`. In the future the method may
load CA certificates from other locations, too.
