webkitpy results are failing with the patch.
You can run them using Tools/Scripts/test-webkitpy.

I am not sure about slash, since we might at some point move away from Cygwin.
Given that this is done extensively in this file, this might be ok...

> Tools/Scripts/webkitpy/common/checkout/scm/svn.py:302
> +            patch = patch.replace(relative + '/', '')

In that general context, it is not sure that it will do exactly what we want.
This is fine in the context of the exporter.
I would add a comment here stating that the relative parameter should be chosen carefully or a better svn-specific approach be taken.

> Tools/Scripts/webkitpy/w3c/test_exporter.py:211
> +        patch_data = self._host.scm().create_patch(git_commit, [WEBKIT_WPT_DIR], relative=WEBKIT_WPT_DIR)

You might need to update Tools/Scripts/webkitpy/w3c/test_exporter_unittest.py as well

r- because SVN implementation is inadequate.

> Tools/Scripts/webkitpy/common/checkout/scm/svn.py:303
> +            relative_path = relative if relative.endswith('/') else relative + '/'
> +            patch = patch.replace(relative_path, '')

This would replace any string which contains this string. That could be problematic inside Source.
Do a regex match against file names protruded in lines 392-395 in ./Tools/Scripts/svn-create-patch

But a better fix is to add an option to svn-create-patch to specify a relative path as you've done to git.
