svn diff -c: Omitting copied files?

If I copy a file in the repository using the svn copy command, the "svn diff -c" command will show all lines of the copied files. How can I omit copied files from showing in the diff?

If I view the changeset of the revision in Trac for example, no diff is shown (just says the file is copied).

This is the command I use: svn diff -c REVISION SVNURL --username USERNAME --password PASSWORD

Thanks in advance!

Here is a solution that requires a bit of programming:

svn log URL -c REVISION --xml -v

With this command you have a clear indication of what was copied. You can then parse the XML output and use it to filter the output of svn diff -c

Example of output:

<?xml version="1.0" encoding="UTF-8"?>
<log>
<logentry
   revision="REVISION">
<author>EMAIL</author>
<date>YYYY-MM-DDTHH:MM:SS.UUUUUUZ</date>
<paths>
<path
   copyfrom-path="/OLD_PATH"
   copyfrom-rev="OLDER_REVISION"
   action="A"
   prop-mods="false"
   text-mods="false"
   kind="dir">/NEW_PATH</path>
</paths>
<msg>Copy a file</msg>
</logentry>
</log>
