I wrote a script that allows you to filter svn diff output to exclude changes based on metadata and file names (or anything else on the first line that can be greped).
I wrote it to remove all of the “properties” changes and filter out the output files, so all that was left was the code changes and a list of binary files that were modified.
Just pipe the output of svn diff to the script, after you set the parameters at the top of the script. I put the filters in the script instead of parameters because I always run the same filters.
It is released under the GPLv2 (the licensing details is longer than the script itself).
