Subject: job control stuff in tracepoint.c

Ok, I'm looking into cleaning up some host-dependent stuff;
autoconfigifying bits and so on.

I'm currently looking into stuff dealing with job-control signals
(SIGTSTP. sigprocmask, sigsetmask).  In that context we also do some
really wierd stuff with a macro called STOP_SIGNAL.  The reason for
its existence has been eliminated (broken job-control handling on the
Convex, support for which has been removed), yet it still exists.  I'd
like to eleminate STOP_SIGNAL (and revert to using SIGTSTP where
appropriate), but when I did that I discovered that STOP_SIGNAL is
used in tracepoint.c wheras it isn't defined at all, not even to
SIGTSTP.  Replacing #ifdef STOP_SIGNAL, with #ifdef SIGTSTP leads to
compilation failure since the variable job_control isn't declared.

I'm not quite sure what the code is trying to do.  Something with
redisplaying the prompt when running asynchronously?  Elena, can you
shed some light on this?
