To me it's easy to spot, but there is nothing wrong with it that the
shell will spot, so that is a downside. Whatever we go with, it would
perhaps be less error prone to set "NOPREREQ1" when we don't have
PREREQ1, and check that either $1 or NO$1 is set when checking
prerequisites. But that is probably just over-engineering. This is not
an error we have seen a lot of, and it is not that hard to spot with
code review.
