HardPressed + GWIII

[fadden@uts.amdahl.com (Andy McFadden)]

Don't try to read compressed files or files in marked folders into
GraphicWriter III with HardPressed running.

Turns out that (stupid stupid stupid) I was clearing or setting the N
flag instead of the Z flag when returning from a GS/OS call.  This caused
GW III to think a SET_MARK call had failed, which it handled by repeating
the series of GS/OS calls until something overflowed and it crashed.

Enterprising folks can dig through the binary (about $800 bytes in) and
change the offending SEP #$80 / REP #$80 to $02.  This is so silly I'll
probably write a patch program and u/l it; keep an eye out.

I'm fairly amazed that nothing else choked and died, actually.
