   newfunction(:join_keys_to_values, :type => :rvalue, :doc => <<-EOS
 This function joins each key of a hash to that key's corresponding value with a
-separator. Keys and values are cast to strings. The return value is an array in
+separator. Keys are cast to strings. If values are arrays, multiple keys
+are added for each element. The return value is an array in
 which each element is one joined key/value pair.
