This seems fine as a solution for now. I tried to keep the transport
code mostly independent of the local repository settings, but in this
case because the HTTP walker mucks around with the internals of the
local pack files, I don't think we can avoid this without some major
restructuring, which I'm not interested in sitting down and writing this
evening.
I'll clean this up in a nicer way once I get interop working. Thanks
for sending a patch for this.
