Summary: Map and for-each should work even if lists are of unequal length

The R6RS definitions of "map" and "for-each" should permit the list
arguments to be of unequal length, and specify that they terminate
when the shortest list runs out. This is what SRFI-1 does, it is
cheap, and it is useful.

One Word to write them all,             John Cowan <cowan_at_ccil.org>
  One Access to find them,              http://www.ccil.org/~cowan
One Excel to count them all,
  And thus to Windows bind them.                --Mike Champion
