Description of problem: Some patches are displayed incorrectly so that important information are missing. E.g. the patch in bug #800601 https://bugzilla.redhat.com/attachment.cgi?id=572385&action=diff shows in a/dietlibc-0.33.20111222_make-arm.patch only 9 lines (a removal of MYARCH := ...). When you look at the raw patch https://bugzilla.redhat.com/attachment.cgi?id=572385 you will see that there is one line more (a new MYARCH := ...).
This was fixed upstream in Bugzilla 4.2. We will inherit this change when we move to Bugzilla 4.2. -- simon
