I have seen similar behaviour to what Fred sees, but I can't remember if
that was u2d or d2u. In that case the files had mixed use of \n and \r\n
line endings. I presumed d2u/u2d detected a single \n (or \r\n) in the first
X bytes, and assumed the file was already in the appropriate format.

I 'fixed' this by running u2d then d2u (or vice versa).

Dave.
