Comment:
Done; the patch declares the function as static, meaning that the patch should immediately fail to compile when 1.9 is released and qcopy_file_preserving is declared "extern int...", and slightly modifies the original patch by commenting out `#include "copy-file.h"` as everything is done in a single file.

If I screwed up anything let me know.
