[Gm2] Using IOChan.RawRead() on StdChans.StdInChan()

[SiTex Graphics]

Hi Gaius,

I've asked about this before, but it seems to have fallen through the
cracks.  I'd like to be able to read from stdin using
IOChan.RawRead().

The raw flag just needs to be added to the following in StdChans.mod:

stdin :=MapFile(FIO.StdIn, read+text);  (* needs +raw *)

Can that be added to the standard distribution?

Thanks,
Scott
