 * The kill ring class keeps killed text in a fixed size ring. In this

 * kill or a yank. Depending on this, the class may behave
 * different. For instance, two consecutive kill-word commands fill

 * previously killed words instead that only the last one. Likewise
 * yank pop requires that the previous command was either a yank or a
 * yank-pop.
