I checked both the grep on macOS (2.6.0-FreeBSD) as well as GNU grep (3.11) and I can't figure out why this would produce different results on any version of grep. The only difference I see here is that we now allow:: and//, etc.

Or are you suggesting that a remote may be namedgithub.com:/coder/coder and you wanted to add support for that?Edit: I re-read your description and that was indeed what you were going for. I thought ^this is an illegal format on GitHub but if not, have at it 👍🏻

Approving to unblock though since it's not a harmful change.
