+ * A punctuation delimiter, used only in mdoc(7) documents, is opening,
+ * closing, or "middle mark" punctuation.  These govern spacing.
+ * Opening punctuation (e.g., the opening parenthesis) suppresses the
+ * following space; closing punctuation (e.g., the closing parenthesis)
+ * suppresses the leading space; middle punctuation (e.g., the vertical
+ * bar) can do either.  The middle punctuation delimiter bends the rules
