Update to 1.10.8:

24-12-2010: version 1.10.8

Significant improvements merged from OpenBSD downstream, including

    * many new roff components,
    * in-line implementation of troff's soelim,
    * broken-block handling,
    * overhauled error classifications, and
    * cleaned up handling of error conditions.

Also overhauled the -Thtml and -Txhtml output modes. They now
display readable output in arbitrary browsers, including text-based
ones like lynx. See HTML and XHTML manuals in the DOCUMENTATION
section for examples. Attention: available style-sheet classes have
been considerably changed! See the example.style.css file for
details. Lastly, libmdoc and libman have been cleaned up and reduced
in size and complexity.
