Handle 307 redirects in hc-login (#35)
Properly handle 307 redirects, in the same way 302 redirects are already handled. See issue #35 and https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#3xx_redirection.
Had the same issue too. Testing is tricky but the code looks fine and does not break something else.
I agree that testing is a problem. I was not able to find any documentation for singlekey-id.com, so best I can do is assume they strictly follow Oauth. But Oauth should never return a 307, so I'm slightly confused there.
In either case the hc-login script doesn't finish successfully for me. So I can't guarantee that 307 forward does/doesn't get me closer to a working setup.
