+Subject: [PATCH] READ-ONE-LINE: Turn COMPLETIONS into a keyword argument
+
+This keeps READ-ONE-line backwards compatible to changes prior
+dae0422811771d179077b9336618f2b19be85b7b. Currently both
+ARGUMENT-POP-OR-READ and ARGUMENT-POP-REST-OR-READ are still being
+called with the previous lambda list. Update the calls to the
+READ-ONE-LINE that used the 'new' lambda list, COMPLETING-READ and
+YES-OR-NO-P.
+
+Closes #538
