lib/parser: Add missing closing div tag (OSGeo#2523)

End of file is being added both in parser and also in mkhtml because it is removed so that documentation can be just appended. This marks the closing tag with a comment so that the right line is removed.

(An ultimate solution is moving to more template-like replacement instead of the current file append.)
