That's a good point --- and, in fact, creating *whole* arrays isn't a
problem, either, unless we think we're protecting against
stuff=($(<bigfile))
and I don't think we are; why is that more problematic than the
unprotected
stuff="$(<bigfile)"
?
However, this has now turned from a simple change to a research project.
