Harvest 3 missing fixes from http://bugs.squeak.org/view.php?id=6367

1) Create a CharacterSetComplement on a copy of the original (to avoid modifying the original when modifying the complement)

2) Create a postCopy to avoid modifying the original when modifying the copy

3) Correct a type in hash

Strange, I thought it was already harvested in 3.10 ...
