I think the exit-code condition doesn't necessarily mean that the
script is unsuccessful. It may be used as a mere non-local exit
when the exit code is something innocent like 0.

For example a parser of script parameters might exit this way when it
recognizes --help or --version, to leave the normal control flow for
the normal usage of the program.
