Argument types with dot not properly handled.

[Constantin Kulikov]

Thanks for fixing my previous issue. And I found another one.

Test case:

import "time"

type test_interface interface{
    test_mf(arg time.Duration)
    test_ms(time.Duration)
}
func main() {
    var ti test_interface
    ti.test_mf()
    ti.test_ms()
}

And, probably, fix:

"\\(" go-identifier-regexp "\\(?:\\." go-identifier-regexp "\\)?\\)"
