   It seems to me that patch(1) should just recognize and handle this
   situation.  The correct behavior is obvious - accept CRLF and LF (and
   CR) line endings, apply the transformation preserving the current
   line-ending format of the target file.  Diffs do not work on binary
   files anyway.

   You could also consider this a special case of Karl (IIRC)'s
   intelligent patch-merging algorithm.
