Loosely validate a URL.
From [npm's package.json docs](https://www.npmjs.org/doc/package.json.html#Git-URLs-as-Dependencies), Git urls can be of the form: - git://github.com/user/project.git#commit-ish - git+ssh://user@hostname:project.git#commit-ish - git+ssh://user@hostname/project.git#commit-ish - git+http://user@hostname/project/blah.git#commit-ish - git+https://user@hostname/project/blah.git#commit-ish Not sure it's appropriate to support these kinds of...

It fails on this URL https://chat..zulip.org. https://chat..zulip.org --> true https://chat.zulip..org --> true https://chat.zulip.org.. --> true and it should be false.
I tried to fuzz the library again using GramTest, a grammar based test case generation tool (https://github.com/codelion/gramtest). I found that it fails to to check mailto URLs. `isUrl('mailto:[email protected]') // false`
