StopAllCoroutines should clarify that it only works after using "StartCoroutine"

Hi,
I had this issue today where StopCoroutine wasn't stopping my Coroutine, after tons of research, I gave up and decided to use "StopAllCoroutines", to my surprise, that also didn't work. and the reason was because my coroutine wasn't started with:

Code (CSharp):

1. StartCoroutine(MyCoroutine);

Instead, it was a nested coroutine that was started with:

Code (CSharp):

1. yield return MyCoroutine();

And this can't be stopped with neither StopCoroutine nor StopAllCoroutine.

so I think StopAllCoroutine documentation should be fixed, considering that its description says:
"Stops all coroutines running on this behaviour."
When in reality it only stops all coroutine on this behavior that have been started with StartCoroutine.

Thanks!
