This check was redundant, because `errors.Join` already checks if the
list of errors is either empty, or only contains `nil` errors, as can
be seen in [this example][1];
package main
import (
"errors"
"testing"
)
func TestMultiErr(t *testing.T) {
var errs []error
if err := errors.Join(errs...); err != nil {
t.Fatal(err)
}
errs = append(errs, nil, nil, nil)
t.Logf("errs contains %d elements", len(errs))
if err := errors.Join(errs...); err != nil {
t.Fatal(err)
}
errs = append(errs, errors.New("with an error"))
if err := errors.Join(errs...); err == nil {
t.Fatal("expected an error")
}
}
