This is an idea to have checkdoc propose "non-nil" at the start of
docstrings, rather than "true".
For variables this is per the last tip in "(elisp)Documentation Tips".
The functions bit extends on similar lines.
Maybe the function form could report further variations, eg. `eventp'
starts "True if the argument ...".

I think this makes sense. Any objections to applying?
