| But as it happens, the writers of the POSIX standards *did* use that
| word in some places, and so we have to live with it.
The usage much predates POSIX or any of the previous standards.
It is how it was originally documented.
| Back to the original topic, I have absolutely no idea what "${a[@]:+word}"
| is supposed to do.
Nor do I. It might mean $# -ne 0 (or in this context ${#a} -ne 0)
or it might mean similar to
for f in ${a[@]}
do
test [ "$f" ] && return 0
done
return 1
or something else entirely.
