While that would be nifty, I think some simpler changes would help too:

- Have pylint warn (possibly only if a special option is passed, to help
  sharing a pylintrc between pylint versions) if an option in the pylintrc
  is not recognized (currently such options seem to be ignored).
- Have an option to generate a complete rcfile, including options that are
  unset or set to their default value.

While I do not know how others do this, my approach for generating an
rcfile was doing "pylint --generate-rcfile > ~/.pylintrc" and then
editing it. If default/unset values are omitted that does not work
very well, and it was not obvious (not to me at least) that the
"Messages control" header in --help meant I had to use a "[MESSAGES
CONTROL]" section in .pylintrc. The above changes would make it all a
bit more obvious, I think.

If you agree this would help I could try to produce a patch.
