svn generates long lists of empty diffs with --diff-cmd

[Alexey Neyman]

Hi,

I noticed that SVN generates a lot of spurious diffs when using a 
--diff-cmd option that look like this:

Index: arch/alpha/boot/tools/objstrip.c
===================================================================
Index: arch/alpha/boot/Makefile
===================================================================

Is it possible to suppress such empty diffs? This makes the tools like 
ReviewBoard (www.reviewboard.org) examine a lot of unchanged files and 
slows them down considerably and unnecessary.

Regards,
Alexey.
