The patch itself was mangled somehow, maybe your MUA. I think this is small enough that we can accept it without a copyright assignment. If you plan to submit more patches, though, contact me to get started on the paperwork. I am running this through our tester, and if it works ok I am going to check it in. It looks safe enough for 7.3 as well. Tom
