cmd/go/internal/modfetch: avoid http lookup for non-domain paths

Before, if vgo saw import "appengine" it would incorrectly try to
look up https://appengine?go-get=1. Apply the usual domain-name
restriction (dot before first slash) as in plain "go get".

Because the old network lookup also used to loop incorrectly,
at least according to a bug report, test a nonexistent domain
name too.

Fixes golang/go#23967.

Versioned Go Prototype (vgo)

This repository holds a prototype of what the go command might look like with integrated support for package versioning.

See research.swtch.com/vgo for documents about the design.

Download/Install

Use go get -u golang.org/x/vgo.

You can also manually git clone the repository to $GOPATH/src/golang.org/x/vgo.

Report Issues / Send Patches

See CONTRIBUTING.md.

This is still a very early prototype. You are likely to run into bugs. Please file bugs in the main Go issue tracker, golang.org/issue, and put the prefix x/vgo: in the issue title.

Thank you.
