Gzip-encoded `HEAD` responses throw EOFException

requests.head("http://httpbin.org/get", headers = Map("Accept-Encoding" -> "gzip"))

I hit this in the wild while poking at the GitHub API:

requests.head("https://api.github.com/users/ryan-williams")

A work-around is to ask for a non-gzipped response:

requests.head(
  "https://api.github.com/users/ryan-williams", 
  headers = Map("Accept-Encoding" -> "identity")  // ✅ works
)
