Presumably you'll get the same "one big hunk diff" if you use
ediff-files.  Both ediff-files and ediff-directories work (as the name
implies) on files (and directories), not on buffers.  While the two
buffers show similar (or even identical) contents, the corresponding
files are different (contain different byte sequences because of the
different coding-system).
