+% @firstparagraphindent WORD

+% after a section heading.  If WORD is `insert', then do indentat such
+% paragraphs.
+% 
+% The paragraph indentation is suppressed or not by calling
+% \suppressfirstparagraphindent, which the sectioning commands do.  We
+% switch the definition of this back and forth according to WORD.  By
+% default, we suppress indentation.
