question about "svn diff"+"ignore files" (.orig/.rej/~)

Hello,

We have a script that invokes "svn diff" and then annotates
the output for us.

One thing I noticed is that unlike CVS, when invoked on
a "should be ignored file", basically a file that matches
 *.orig, *.rej and *~, then "svn diff" will emit that file
like so:

? foo.orig

CVS however will not emit anything.

Now both SVN and CVS will not emit anything if "diff" is invoked
on the containing directory.

My basic issue is that I'm not sure what to do...

Because of the "? file.orig" output of SVN, my program assumes
that this are files that need adding.

So:
1) any ideas?
2) Is there some way to query SVN about the files that should be ignored
so that I can filter them in my program?
3) Is there a way to get "svn diff" to ignore the file (generate ZERO output)
when this is a file that should be ignored like "cvs diff"?

thank you,
