svn diff --diff-cmd=diff fails if there is a modified binary file

Hello,

the diff command (part of coreutils IIRC) returns status 2 if there is
a difference in binary files (status 1 means a difference in text
files). Subversion apparently only accepts return status 0 and 1.
Attempt to retrieve a diff from repository

   svn diff --diff-cmd=diff -c 3916 svn://localhost/

yields an error:

   svn: 'diff' returned 2

The attached patch fixes the issue for me. Does it look like right/
complete way of fixing this issue?

Thanks!
