I do not have time to review this  2900 line patch analytically, nor to
benchmark it. I have done some functional testing of it on Windows, and
tried to break it in text and CSV modes, and with both Unix and Windows
type line endings - I have not observed any breakage.

This does need lots of eyeballs, though.
