+/* This macro initializes the variables start, end, cnt, cand, and
+ * candend that were passed as arguments from the input parameters b
+ * and s (the candidate list). Start and end are the start and end
+ * BUNs of b that need to be considered. They are relative to
+ * BUNfirst(b) (i.e. not necessarily the start of the heap). Cand and
+ * candend point into the candidate list, if present.
+ * Note that if the tail of the candidate list is dense, cand and
+ * candend are set to NULL and start and end are adjusted instead. */
