Re: Small fix for _copySetConstraintsStmt

Yeah, but listCopy is not the solution, because it'd only copy the cons
cells and not the pointed-to strings.  The representation of
ConstraintsSetStmt is really just plain broken.  It should use a list
of Value string nodes --- which would make copySetConstraintsStmt okay
as-is.  Fixing now...
