Fixed an extremely rare bug where a tag would be partially opened on the board page due to it being cut off by the log message filter. You'll probably never have this happen anyway. Thanks to Anonymo for both of these. git-svn-id: http://kusabax.cultnet.net/svn/repo/stable@180 73d99b7e-4f53-4972-b7b7-2ecd3c4d89ee
