yep, adding \n per se works, and it's essentially what I'm doing. The 
problem is not inserting the \n, but what Octave does to it 
afterward... (slapping braces around the whole thing, which will 
confuse gnuplot...)

did you try it? I think it doesn't work, which can be tested easily:

title("bla\\nblabla")

dumps a "n" in enhanced mode and dumps a literal "\n" without enhanced mode.
