can not clone gopkg.in repo #129
Description
If you run go get -u gopkg.in/russross/blackfriday.v2 in fails to negotiate the pack file when doing the git clone with dgit. If you add debugging prints to dgit, it does get past the ref discovery, but then stops. If you run dgit clone https://www.github.com/russross/blackfriday (the url that gopkg is proxying to), it's fine. The v2 branch also checks out successfully when you clone in that way.
It's weird and needs investigation.
