- Various documentation updates - Fixed fatal error in benchmark scripts, slightly augmented - As far as possible, whitespace is preserved in-between table children - Configuration option to optionally Tidy up output for indentation to make up for dropped whitespace by DOMLex (pretty-printing for the entire application should be done by a page-wide Tidy) - Sample test-settings.php file included Unrelated unmerged edit: removed irrelevant 1.2.0 release notes, those only exist in the trunk. git-svn-id: http://htmlpurifier.org/svnroot/htmlpurifier/branches/1.1@458 48356398-32a2-884e-a903-53898d9a118a
