mailing list archiver chewing patches

Tim Bunce's recent patch has been mangled apparently by the list 
archives. He sent it as an attachment, and that's how I have it in my 
mailbox, so why isn't it appearing as such in the web archive so that it 
can be nicely downloaded? See 
<http://archives.postgresql.org/message-id/20100108124613.GL2505@timac.local>.  
It's happened to other people as well:

Reviewers and others shouldn't have to c&p patches from web pages, 
especially when it will be horribly line wrapped etc. Can we stop this 
happening somehow?

cheers
