cmd/doc: a private field may be listed even when only public fields ought to be.

[lootch]

The following artificial example:

package dummy

type (
    private struct {
        z *int
    }
    Public struct {
        p *int
    }
    Sample struct {
        *Public
        *private
        x *int
    }
)

when inspected with "go doc Sample" yields:

type Sample struct {
    *Public
    *private

    // Has unexported fields.
}

where *private should not appear at all.
