Please, David H - whatever you do with email is WRONG. Fix your completely broken email client. Stop doing this.

[...] Only ve= ry and [...] Withou= t is just completely wrong. You either have a completely broken email client that doesn't handle MIME at all - get rid of it - or you're then dealing with raw mbox data in a completely broken manner without handling MIME wrapping. I can't figure out _what_ you're doing wrong, but the pattern is clear by now: it's not Andrew (although Andrew should check explanations better!), since it _only_ happens with patches from David Hildenbrand. Fix your workflow. Because it's broken. Linus
