I'm not certain: most of the exit codes are 0 (EXIT_SUCCESS) or 1 
(EXIT_FAILURE).  There are a few stray cases, which do not appear to 
apply:

        print_help_and_exit(-1)
        outofmem(-1)

There's a case for subprocess in the NSL_FORK which could return a 2, but 
I don't believe that would come up to the shell.

Executing from a script sounds as if your environment variables may be 
missing $TERM or something like that - but a quick check here doesn't 
produce an error unsetting that.
