Log Message:
-----------
rST parser warns about empty footnotes and citations.

The reStructuredText parser now adds a "warning"-level system
message for footnotes and citations without content block
instead of generating invalid elements.

(Block-level content is mandatory for `<footnote>` and `<citation>`
elements according to the Docutils DTD.)
