Regex Failure

[ghost]

Current regex doesn't match https://github.com/gnomon-/furby-source

Blame the source of the username regex, which has an issue about this problem: shinnn/github-username-regex#4

It seems the username rules about trailing hyphens changed at some point, but GH allowed existing accounts to keep them.

(If you want to throw more fun into the FOSS world, one of the test cases in GrantBirki/github-username-regex-js's readme is a trailing hyphen that's expected not to be valid 🙃)
