Here is a super-trivial document patch to the reference
manual.

Bug: punctuation error.

2000-05-02  Mike Gran  spikegran@earthlink.net

        * preface.texi: Minor punctuation mistakes.  Hyphens
              should link compound adjectives.  Commas should be
              placed after a "therefore" that begins a sentence.
              Commas should not be used to separate a list of only 2
              dependent clauses.
