I stumbled across why the Death Quotes hadn't been getting displayed
evenly before being recycled:  ones I've added since 3.6.0--probably
even before the release--were unintentionally missing their '%e passage'
directive, so attempted look-up for those returned the very last one
(terminated by '%e title').  The recent change to read_passage() has
made '%e passage' be optional for one-line death quote passages, so
this patch doesn't bother putting them in.
