And another small editorial fix.   In mapping-catenate!, two procedures are referred to as old names mapping-map/catenate and mapping-map/catenate!.

The signature of mapping-catenate in the spec is

But in the reference implementation it is

   (mapping-catenate comparator mapping1 key value mapping2)

Since the description of the spec refers to the comparator argument, I think its signature is missing it.
