Something broke a bit of logical inference in the build system. Without the inference that comments were allowed, they weren't. Fixed now.
Crud. I upgraded some bits a week or so ago and comments stopped working. Why logical inference is necessary to enable comments is an intresting story about authoring laziness, RDF, and open world assumptions.
But I don't have time to tell that story right now.
Comments:
I think that's a story I'd like to read, when you have the time.
