\programopt: New macro, used to mark command-line parameters in the

              text.  Looks like \program.

\citetitle:   New macro, used to mark titles of cited works (like the
              names of the Python manuals).  Accepts & discards an
              optional parameter that is only used by the HTML
              formatter.  Looks like \emph.
