Daimona Eaytoy 07e5168eb9 Add a maintenance script to fix broken log entries
A very simple fix for some old entries imploded with '\n' instead of
"\n". As for other scripts, this extends LoggedUpdateMaintenance but it
includes a dry run option to be tested, and a subsequent patch (to be
merged after testing) will add it to update.php.
