Yarn install in v1.6.0 with dependency from private repo starting with `ssh+git` fails "Invalid protocol: ssh+git:".

Doing yarn install in v1.6.0 with a dependency from private repository, pointing to a url that starts with ssh+git fails.

[2/4] Fetching packages...
error An unexpected error occurred: "Invalid protocol: ssh+git:".

Changing it to git+ssh seems to fix the issue.

Yarn: v1.6.0
Node: v8.9.1
OS: Ubuntu

I suppose this should be supported since git clone supports that protocol. I can't seem to actually find any git docs that list every valid possibility (git:, ssh:, git+ssh:, ssh+git:, etc...)

Should be a fairly easy fix, but as you already discovered, using git+ssh will work.

I would assume Yarn would only support the same protocols from NPM.

See https://docs.npmjs.com/files/package.json#git-urls-as-dependencies for more information.

This docs says about git, git+ssh, git+http, git+https, or git+file protocols. I've prepared fix for this but I'm not sure we want to add it and simply close the issue.

That's a good point. Seems like it's just backwards: git+ssh vs ssh+git.

I also found that a github shorthand exists in the later Yarn versions: <org>/<repo>#<branch> works without any specific protocol. It will try HTTPS and then SSH (AFAIK).
