That fails on at least three cases: -- comments, newlines separating
parts of quoted literals (cf bizarre SQL spec requirement that adjacent
literals are merged only if separated by a newline), and newlines
embedded in quoted literals.  You could possibly work around the first
two cases by doing nontrivial editing of the query string, but I see no
way around the last one.
