Reference git url with hash (i.e. for multi repo PR's)

[jouni-kantola]

Do you want to request a feature or report a bug?
I guess it's a Feature, but works in npm CLI

What is the current behavior?
When I reference a GitHub URL with hash, I get the error message:
error Couldn't find any versions for <module> that matches git@github.com:user/repo.git#abcd1234. Possible versions: 1.0.0

If the current behavior is a bug, please provide the steps to reproduce.

1. Create a PR in git repo
2. Reference the commit's git URL in package.json ("module": "<url#hash>")
3. yarn install
4. error: needs package version

What is the expected behavior?
We're using multiple git repositorys. At times we need to reference a PR commit by hash for testing, like git@github.com:user/repo.git#abcd1234. This would help if it works (which it does with the npm CLI).

Please mention your node.js, yarn and operating system version.
node.js: v6.4.0
yarn: 0.15.1
Windows 10

Referencing a branch with a hash works fine in yarn.

What doesn't work is the fact that you're specifying git@ as the user, which is an open issue at #513.

Using the workaround at #513 (comment), specifying a source of ssh://github.com/user/repo.git#abcd1234 will pull the abcd1234 branch and work fine.

@milosivanovic: Thank you; that worked well.
