cmd/go/internal/modfetch/gitrepo: work around old git fetch hash behavior

For the git fetch --depth=1 attempt:

1. Use a ref instead of a hash if known.
2. Check for the older "no such remote ref" error in addition to the newer "unadvertised object" error.

Fixes golang/go#25102.

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.
