+       Clean up handling of median, by treating it almost like any other
+       percentile.  Fixes bug #17424.  Thanks to John Darrington for
+       review.
+       * frequencies.q (internal_cmd_frequencies): Fix handling of bit
+       masks for `stats' variable.  If median is selected, turn it off
+       and add a 50th percentile.
+       (add_percentile): Simplify code a little.
+       (calc_stats): Drop special casing of median.
+       (dump_statistics): Ditto, except that we label the 50th percentile
+       as "50 (Median)" to make it clear that it's also the median.
