\seemodule: Fix so that each \seemodule entry gets its own paragraph,

so they don't get run together when there's no blank line
	between them in the source.  The HTML conversion already did
	the right thing.

\refmodule:  Refer to a module, using a hyperlink in the PDF version.
	Visually the same as \module.
