create_instance() documentation typo

[Former user]

Documentation typo in orm/interfaces.py (rev 3755)

The method can choose to create the instance itself, or it can return
None to indicate normal object creation should take place.

but in source code None value not acceptable (mapper.py line 1414).

It seems that None must be replaced with EXT_CONTINUE (or EXT_PASS for 3.xx).
