What search string did you use to find that?  That may be more interesting than
my original question.

Reading that page, I found the explanation that an exit through a trap might
give a different exit status with a simple


exit 1


because the exit status will be that of a command run in the trap and the more
complex


{ (exit 1); exit 1; }


preserves the intended exit status.  But I don't understand that.  It seems to
me that if that unintended exit status obtains with the simple command, it will
with the more complex command too.  Evidently either I misunderstood the Web
page or I'm missing something.
