Thank you for including the patches and reporting this, Stephen.
Is this a warning you can live with for a week or two?

I've never tried generating htmldocs (I'm tempted just to replace a few
"/**"s by "/*"s!), and I'm fairly sure Matthew will have strong feelings
about how this new union (or not) will be better foliated - me messing
around with doc output here is unlikely to be helpful at this moment.
