I spent a couple of minutes and made the attached (pretty bad) patch to add a del-header-by-prefix.
Unfortunately, I made it off of master before noticing that master segfaults on every request, so I haven't tested it yet. At least it compiles... Feel free to use it, throw it away, or whatever else suits your fancy.
