Update to 3.20100704. From the changelog:

   * Changes to avoid display of ugly google openids, by displaying
     a username taken from openid.
   * API: Add new optional field nickname to rcs_recentchanges.
   * API: rcs_commit and rcs_commit_staged are now passed named
     parameters.
   * openid: Store nickname based on username or email provided from
     openid provider.
   * git: Record the nickname from openid in the git author email.
   * comment: Record the username from openid in the comment page.
   * Fixed some confusion and bugginess about whether
     rcs_getctime/rcs_getmtime were passed absolute or relative filenames.
     (Make it relative like everything else.)
   * hnb: Fixed broken use of mkstemp that had caused dangling temp files,
     and prevented actually rendering hnb files.
   * Use comment template on comments page of example blog.
   * comment.tmpl: Fix up display when inline uses it to display a non-comment
     page. (Such as a discussion page.)

     runs.
