Actually, I think it has something to do with the new line char "\n", I
don't recall exactly, but the "\n" when passed from lua is not seen as a
new line char at tex end. Removing te two occurrences of "\n" in your
code will git ride of the omegas. If you want to pass new lines to tex,
why not doing tex.print() in the substrings directly instead of
concatenating every thing first.
