I've added a section to the manual documenting nnfeed (without going too
far into implementation details, which are available in the comments and
docstrings of "nnfeed.el"), and amended the the section documenting nnatom.
I've also documented nnfeed in NEWS.

I think this can be merged now.  Updated patch attached.

Thanks,
Daniel
