diff don't recognize all changes in keyword expansions

Hello,

I committed a file which was still opened in my editor. Then I changed
something and, even though my editor warned me, that the file has changed
since reading it, I saved it. The output of the following 'svn diff'
surprised me: The change was caused by keyword expansion.

Voila, a reproduction recipe:

        zeisberg@cepheus:/tmp$ svn --version | head -n 1
        svn, version 0.34.0 (r7859)

        zeisberg@cepheus:/tmp$ svnadmin create repo

        zeisberg@cepheus:/tmp$ mkdir project

        zeisberg_at_cepheus:/tmp$ svn import -m '' project file:///tmp/repo

        Committed revision 1.

        zeisberg_at_cepheus:/tmp$ svn co file:///tmp/repo wc
        Checked out revision 1.

        zeisberg@cepheus:/tmp$ cd wc

        zeisberg@cepheus:/tmp/wc$ echo '$Rev$' > file

        zeisberg@cepheus:/tmp/wc$ svn add file
        A file

        zeisberg@cepheus:/tmp/wc$ svn propset svn:keywords "Rev" file
        property 'svn:keywords' set on 'file'

        zeisberg@cepheus:/tmp/wc$ svn ci -m ''
        Adding file
        Transmitting file data .
        Committed revision 2.

        zeisberg@cepheus:/tmp/wc$ cat file
        $Rev: 2 $

        zeisberg@cepheus:/tmp/wc$ echo '$Rev$' > file

        zeisberg@cepheus:/tmp/wc$ svn diff file

        zeisberg@cepheus:/tmp/wc$ svn status file

        zeisberg@cepheus:/tmp/wc$ svn revert file

        zeisberg@cepheus:/tmp/wc$ cat file
        $Rev$

Shouldn't the diff and the status command notice the change in the keyword?
And imho revert should reset the change.

Regards
Uwe
