Incomplete detection of github URLs

[ahknight]

The detection for github URLs is missing the following cases:

git+ssh://[email protected]/user/repo.git
https://user:[email protected]/user/repo.git

The latter is needed for integration with Xcode CI as Xcode ships off your current git URL to the server, which won't have your SSH keys, etc. So it would be nice if the detection understood URLs a little better (a more expansive grep regex would do it).
