DMN12 — Wrong length range check for built-in function sublist() and substring()

Footnote 2 of table 61 contains wrong check, therefore change footnote 2, to: "length must be in the range [1..E], where E is L - start position + 1 if start position is positive, and -start position otherwise."

The "+ 1" is important!

Example: sublist([1,2,3],1,3)
--> length must be in the range from [1..3] not [1..2]

Same applies to built-in function substring(), table 60 page 133, footnote 1, second sentence.

correct the range of the length arg of 2 builtins
