cmd/go/internal/list: implement and test list -m -e for plain arguments

We were being lazy treating arguments like "foo" as a pattern.
That produced the weird output:

	warning: pattern "foo" matched no module dependencies

Instead, non-pattern mismatches as actual errors, making
them available to template patterns and also making the list
command fail for bad module names.

Inspired by golang/go#24149, which is already fixed by
the new loader. Added a test for that case too.

Fixes golang/go#24149.

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.
