If a subpage contains "#REDIRECT [[../]]", it will not display as a redirect, it will display as a numbered list with one element, a link to the parent page (so the .. does get correctly identified as a link to the parent page). If it contains "#REDIRECT [[../foo]]", the same applies. Neither of these redirect correctly, as the URL shows. "#REDIRECT [[/subpage]]" works normally.
secureAndSplit() returns false because of line 1519 of Title.php ( http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3/includes/Title.php ): if ( strpos( $r, '.' ) !== false && ( $r === '.' || $r === '..' || strpos( $r, './' ) === 0 || strpos( $r, '../' ) === 0 || strpos( $r, '/./' ) !== false || strpos( $r, '/../' ) !== false ) ) { return false; } It might be possible to add '../' to $wgTitleCache in anticipation.

Confirmed still an issue - are Phil's comments still valid?
