Refs #8620.
If we allow any value to remove form fields then we get name clashes
with method names, media classes etc. There was a backwards
incompatibility introduced meaning ModelForm subclasses with declared
fields called media or clean would lose those fields.
Field removal is now only permitted by using the sentinel value None.
The docs have been slightly reworded to refer to removal of fields
rather than shadowing.
Thanks to gcbirzan for the report and initial patch, and several of the
core team for opinions.

The documentation in this tree is in plain text files and can be viewed using any text file viewer. It uses ReST (reStructuredText) [1], and the Sphinx documentation system [2]. This allows it to be built into other forms for easier viewing and browsing. To create an HTML version of the docs: * Install Sphinx (using ``sudo pip install Sphinx`` or some other method) * In this docs/ directory, type ``make html`` (or ``make.bat html`` on Windows) at a shell prompt. The documentation in _build/html/index.html can then be viewed in a web browser. [1] http://docutils.sourceforge.net/rst.html [2] http://sphinx-doc.org/
