download tries https://, then git+ssh://.

By default, downloads are restricted to known secure protocols
(e.g. https, ssh). To override this setting for Git downloads, the
GIT_ALLOW_PROTOCOL environment variable can be set (For more details see:
'go help environment').

If the import path is not a known code hosting site and also lacks a
version control qualifier, the go tool attempts to fetch the import
