[tex-live] minor typo in tlmgr output, and broken file links

[Karl Berry]

    That should be "less than", not "less then".  The offending source
    code line is here:

    % grep -n 'less th' texlive-2008-08/texmf/scripts/texlive/tlmgr.pl
    1144:      print "$pkg: revision in $location is less then local revision, not updating!\n";

Thanks, I fixed that.
