[issue1234985] using some_re.sub() often imports sre.__doc__

[Georg Brandl]

Georg Brandl <georg at python.org> added the comment:

pattern.sub() imports the SRE Python module (to call its subx()) with
PyImport_Import -- that C functions uses a dummy list ['__doc__'] to get
the correct module for dotted import paths.

The import of an additional module is gone now that re is really called re.
