Summary: let-match does not work as documented

Initial Comment:
The example for the let-match function (p. 134 of the
scsh manual) is:

  (let-match (regexp-search date s)
             (whole-date month day year)
  ... body ...)

and the documentation claims that this "evaluates the
body of the let-match in a scope where whole-date is
bound to the matched string, and month, day and year
are bound to the first, second and third submatches."

However, let-match does not behave like that in 0.5.3:
the first variable is bound to the *match record* (not
the matched string as is claimed), the second to the
whole string and the next ones to the successive
sub-matches.

Therefore the documentation or the code should be fixed
so that both agree.

(Notice that if-match transitively suffers from the
same problem).

Thanks.
Michel.
