It's remarkably easy to get this out of the existing API; keep track
of the end position returned by the previous call, and if it's
different from the start position returned by the next call, slice the
line text from the column positions, assuming the line numbers are the
same. If the line numbers differ, something has been eating \n tokens;
this shouldn't happen any more with my patch.
