jEdit version: 4.3pre7 Java version: 1.6.0-beta2 Before 'Add Explicit fold' the content of buffer looks like this ('X' means selection boundaries): <?php Xfunction foo() { }X /* :folding=explicit:*/ ?> After: <?php <!--{{{ --> function foo() { } //}}} /* :folding=explicit:*/ ?> If is between '<?php' and 'function' empty line, then it works OK.
