Yes. However, I believe that this is what the original ensime code
intended to do; it only underlines the newlines themselves because
it's easier to make 1 overlay for all the lines at once and the
programmer didn't notice it was wrong because it happens to give the
desired effect in GUI mode.

Regardless, by experimentation I find that the space at the edge of
the screen takes the face from the final newline, not the last
displayed glyph character in the line. Is this documented anywhere?
