Patch suggestion – has_excerpt() does not check for empty white space

In “theory” the has_excerpt() function is supposed to return FALSE when a post_excerpt is empty, however it does not consider the possibility of “empty white space”.

Ergo, consider the following mod to the function:

function has_excerpt( $post = 0 ) {
    $post = get_post( $post );
    // check if its just empty white-space
    $post_excerpt = trim(preg_replace('/\s+/', ' ', $post->post_excerpt));
    // then return it
    return ( ! empty(  $post_excerpt ) );
}

TO RECREATE:
Simply add a few empty spaces into an “excerpt” in a post and then check it using has_excerpt(), you will see the has_excerpt() returns TRUE, even though to us as humans its clearly “not true”.

EXPECTED BEHAVIOR:
When a $post->post_excerpt is “only empty white-space” then has_excerpt() should return FALSE.
