Update to 2.84
--------------
2.84  2013-08-13T14:25:21Z
      - Added `--smtp-tls` to the output of `man svnnotify`.
      - Removed `--smtp-authtype` from the output of `man svnnotify`.
      - Added `--diff-content-type` option. Defaults to "text/plain" for
        backward compatibility. Patch by Daniel P. Wright.
      - Renamed `Filter.pm` to `Filter.pod`, since it's just documentation.
      - Removed the pod tests from the distribution.
      - Changed the CSS for message `<pre>` blocks to use `white-space:
        pre-line`, so that long lines will be wrapped, but newlines are still
        respected as usual. Thanks to Dave Abrahams for the patch (and the
        persistence).
      - Changed C<to_regex_map> to allow it to match any path in the
        repository, including files, rather than just directories. Patch from
        mscherer.
      - Fixed error when the first line of the commit message is less than 10
        characters long (issue #2).
      - Fixed the "From" and "To" headers so that they are \ 
properly encoded as
        MIME headers (issue #6).
      - Removed the Makefile.PL, which was just passing through to
        Module::Build. That pattern is now deprecated, and Module::Build is
        required for configuration.
