 Hrm.

 I'm guessing this is because https://golang.org/x/xerrors redirects to
 https://godoc.org/golang.org/x/xerrors, but the first page contains
 metadata for the actual git repo. I can only assume the `go` tooling
 understands this magic:
 {{{
 <meta name="go-import" content="golang.org/x/xerrors git
 https://go.googlesource.com/xerrors">
 <meta name="go-source" content="golang.org/x/xerrors
 https://github.com/golang/xerrors/
 https://github.com/golang/xerrors/tree/master{/dir}
 https://github.com/golang/xerrors/blob/master{/dir}/{file}#L{line}">
 }}}

 We can try using https://go.googlesource.com/xerrors or
 https://github.com/golang/xerrors/ instead.
