Following the vndr docs [1]:
$ go get -u github.com/LK4D4/vndr
$ vndr golang.org/x/text
$ git add -A vendor/golang.org/x/text
The targeted 'git add' was because we seem to have versioned some test
files (e.g. vendor/github.com/varlink/go/varlink/varlink_test.go in
8493dba2 (Initial varlink implementation, 2018-03-26, #627). I don't
know why, possibly an old vndr version? But either way, I'm punting
that particular issue to a separate branch.
