[issue23816] struct.unpack returns null pascal strings - [first] bug report

My previous two messages are not clear enough so I delete them. Sorry for the noise. :-(

When unpacking a pascal string, you cannot simply specify a p format character otherwise struct calculate a wrong size of the format. That's why unpack fails. When count conflicts with the length byte, the smaller one is chosen. I think this is consistent with packing.
