Ugh ... ugh, ugh, ugh ...

I just went through two hours of trying to figure out how come my
process sentinel wasn't working.  For some reason (probably lack of
sleep and this bump I have on my head ...) I didn't just put in a
simple (message "called with stat %s" stat); when I finally did I
felt a bit foolish for not having done it sooner.  I also felt a bit
misled :-/

I was reading out of an older version of the manual, but I check the
recently announced manual which I installed in the Info tree here and
found it also slightly inaccurate.  I had been testing for (eq stat 'exit)
when in reality the processes were returning 'finished.  I don't know
if they ever will return 'exit, but the manual surely never mentions
'finished anywhere that I could find.

Perhaps it is my version or something, so here it is:
GNU Emacs 18.53.2 of Tue Apr 11 1989 on imagine.pawl.rpi.edu (berkeley-unix)

By the way, before this thing goes to print are the "(intro!!)"
sections going to be expanded a little?

More fun with processes; I wish the manual had been more clear on this.
What is really sent to the process is not a symbol but a string;
instead of testing for 'exit, what I should have been testing for in
my sentinel was (string-equal stat "finished\n").  Sort of odd that
the newline is in there, but it is.

Boy, do I feel stupid.
