Subject: [PATCH/resend] gitk: Handle 'copy from' and 'copy to' in diff headers.

From: Johannes Sixt <[email-masked]>
Date: Mon, 20 Aug 2007 15:27:54 +0200

From: Johannes Sixt <[email-masked]>

If a commit contained a copy operation, the file name was not correctly
determined, and the corresponding part of the patch could not be
navigated to from the list of files.
