Subject:	debug32 and demacs

I do know the reason for the demacs problem:
(For those who didn't read the original message:
After escaping into a subshell via C-Z, demacs
sometimes reports a "dos shell not found error".)

The reason for that is that demacs reports any
return code != 0 from the subprocess as the above
error.  However, my command.com (and 4dos as well)
return a random value upon plain exit.  Under
4dos, a have a "4exit.btm" file which just contains
an "exit 0" statement.  I don't know if command.com
supports an argument to exit.  In that case, you might
have to change the demacs source code, which has some
other bugs as well related to subprocesses.
