svn_client_diff messed up output with external diff command problem

I have a pysvn user that found the output of diff messed up compared
to the
svn command line diff.

He gets output like this:

Index: some/file
==================================OUTPUT
FROM
DIFF====================================

instead of:

Index: some/file
======================================================================

OUTPUT
FROM
DIFF

He tracked this down to the way pysvn calls svn_client_diff. pysvn uses
svn_io_open_unique_file3 to create the output and error file objects.

It seems likely that because these are APR_BUFFERED the output of svn
and the external diff command do not get merged correctly.

Do you consider this a bug in SVN or in how pysvn calls SVN?
