Run without `set -u' enabled. Bash-4.0 was changed to include $@ and $*
in the variables subject to `set -u'. Those expansions will exit the
shell when there are no positional parameters.
(There is a problem with this: ${@:-foo} also exits the shell with an
unbound variable error. I'm working on a fix for that.)
