cmd/cover: doesn't respect examples

[metakeule]

What does 'go version' print?
1.3

What steps reproduce the problem?
If possible, include a link to a program on play.golang.org.

1. create a package
2. create a test case as example
3. run go test --cover

What happened?
the example does not contribute to the coverage

What should have happened instead?
the example should contribute to the coverage since it's
a test and run with go test

Comment 2:

I am unable to reproduce this. Coverage works fine with examples.
Are you including an "Output:" comment in your example function? If not, the example
won't be executed as a test. Use "go test -v" to make sure your examples are being
executed.
Here's my successful test run:
~/src/covertest $ cat foo.go
package foo
import "fmt"
func Foo() {
    fmt.Println("yay")
}
~/src/covertest $ cat foo_test.go 
package foo
func ExampleFoo() {
    Foo()
    // Output: yay
}
~/src/covertest $ go test -v -cover
=== RUN: ExampleFoo
--- PASS: ExampleFoo (0.00s)
PASS
coverage: 100.0% of statements
ok      covertest   0.010s

You are right: "// Output:" was missing. Sorry for the noise.
