This brings things much closer to correct operation (I hope).
- The shift to only moving the cursor on input (<Someone>'s
changes) had a lot of complications, among them was
that sometimes, there is no more input. When the program was
exiting, or bombing the cursor synch never got done, so the
final messages could end up strewn any place the cursor
happened to be dwelling.
- There were two competing output systems in use: the
wintty stuff for the game, and the msmsg and error stuff
used by the sys/share/pcsys, sys/share/pctty, and
sys/share/pcunix routines. Those were meant to mimic
output to stdout, where stuff just got sent to a sequential
display. Over time, there were calls mixed in that depended
on the cursor tracked stuff from the core game, so you
really couldn't be sure where things were going to display.
It wasn't as much of an issue before, because the cursor
really did get moved around as expected. Everything
now ends up in the same output system.
- I even found a use of the real putchar() because
sys/share/pcunix didn't #include wintty.h the same
as the other files, and the macro never got defined.
Who knows where that character was being put -
the game certainly couldn't track it.
While everything I knew to be wrong yesterday is
now working, there may be some other glitches
lurking that I haven't discovered yet.
Please: test, test, test.
