[Oberon] pcreceive.sh not working for files that are multiples of 255

Thanks very much for pointing this out (it seems your email only emerged
today, even though it looks like you sent it nine days ago).

I just had a quick look, and to me the last half of PCLink_RData in
pclink.c suddenly appears to be utter rubbish - I humbly apologise, it's
obvious (now you point it out) that the PC needs to send (ie, emulate
having sent) a final zero-length (ie 1 byte) packet in these cases.

But I don't like the look of the rest of my code there either, so I think
it needs a really good coat of looking at, as a Mancunian colleague of
mine used to say...

Mea culpa
Paul
