testing: wrong example in package docs for unexported identifier

[Tomasz-Smelcerz]

The following text from the description of the package is at least misleading:

// If the test file is in the same package, it may refer to unexported
// identifiers within the package, as in this example:
//
//      package abs
//
//      import "testing"
//
//      func TestAbs(t *testing.T) {
//          got := Abs(-1)
//          if got != 1 {
//              t.Errorf("Abs(-1) = %d; want 1", got)
//          }
//      }

it may refer to unexported identifiers within the package, as in this example:
And then, in the example, we have an exported Abs identifier?

The Abs is then used in the next example, that refers to exported identifiers, and that usage is correct.
But the mentioned first example confuses the reader.
