I have two files with the same name (extracted from two svn
repositories) one of which has a coding system of undecided-dos, the
other is undecided-unix.

WHen I perform an ediff-buffers between the two files loaded into
emacs I get - correctly - zero reported differences. However if I look
at the differences using ediff-directories I get a single difference
region consisting of the whole file.

If I manually set the coding systems in the two files to be identical
then ediff-directories works correctly reporting no differences.

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).

Caveat: I haven't followed this thread, but this sounds similar to bug #1183.

I believe that the #1183 thread ended with Eli asking Michael Kifer to have
Ediff let you know that the two have the same (or similar) content but different
coding systems and hence different byte sequences.

Perhaps that never got fixed/finished?

Caveat: I haven't followed this thread, but this sounds similar to bug #1183.

I believe that the #1183 thread ended with Eli asking Michael Kifer to have
Ediff let you know that the two have the same (or similar) content but different
coding systems and hence different byte sequences.

Perhaps that never got fixed/finished?

It sounds to me that this is more of a feature request than a bug at
this point. If anyone disagrees, let me know, otherwise I'll reclassify
