Thanks for the advice.  The new version looks like this.  
  (setq font-lock-defaults '((nrnhoc-font-lock-keywords)
                             nil ; do not do string/comment highlighting
                             nil ; keywords are case sensitive.
  (modify-syntax-entry ?_  "w")
  (modify-syntax-entry ?\n  "> b")
  (modify-syntax-entry ?/  (
                            if (string-match "XEmacs" (emacs-version))
                               ". 1456"
                             ". 124b"))
  (modify-syntax-entry ?*  ". 23")
  (modify-syntax-entry ?\^m  "> b")

Much prettier.  And it seems to work too.

Thanks for looking at the code.  From the looking-at documentation,
it seems like it only matches regexps after the point, whereas in the
current way of doing indentation I need to match symbols anywhere in
the line, in most cases at least.  So it's not clear to me how
looking-at will help, unless I rethink the indentation code.
