Subject: bug#3229: 23.0.93; ediff-directories isn't buffer coding system independent
Date: Wed, 06 May 2009 10:41:05 +0100

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.
