Apparent discrepancy between online documentation and how the code works for custom File Storage system

Description

The online documentation for writing custom File Storage systems says that the _save method must be overridden and "No return value is expected." (http://docs.djangoproject.com/en/dev/howto/custom-file-storage/#save-name-content).

However, the inherited save method in django/core/files/storage.py contains these lines (45-48):

name = self._save(name, content)

# Store filenames with forward slashes, even on Windows
return force_unicode(name.replace('\\', '/'))

The obvious problem is that returning nothing from the _save method causes the last line to throw an error like this:

AttributeError: 'NoneType' object has no attribute 'replace'

From what I can tell, the documentation should state that the _save method should be implemented so that it returns the name of the file that was written to in the end. This seems to be consistent with how the code is really implemented and how the FileSystemStorage class is implemented in the same file.
