go fix applied the modernizers: promoted-field keys in struct literals,
strings.Cut, SplitSeq, new(expr), slices and maps helpers, wg.Go, reflect.TypeFor
and errors.AsType. omitzero is left out, since omitting a zero struct such as
time.Time{} is a per-field wire decision and not a mechanical one.
Two changes the modernizers could not make for themselves. AsType needs its type
argument to be an error, so the git exit-status reader embeds error in the
interface it asks for. And an error built by concatenating a tag list into its
own format string now says so with a verb, which is what vet was pointing at.
