Niall Pemberton resolved IO-254.
--------------------------------

    Resolution: Won't Fix

The main purpose of this method is to compare the contents of files which do exist. It needs to gracefully handle non-existent files, which it does. Its an edge case comparing the content of two non-existent files and you could argue it either way. Its worked this way since IO 1.0 and the comment in the code clearly indicates it was intentional and therefore I don't think we should be changed.

> It is said in the documentation, that:
> "This method checks to see if the two files are different lengths or if they point to the same file, before resorting to byte-by-byte comparison of the contents. "
> Does it make sense to return true when the file does not exist even if comparison of a file to itself was attempted?
