My suggestion above was to support both these goals.
1. Having the last command win and doing it in reverse order gives the
same precedence as having the first command win and doing it in forward
order.

2. By registering all commands, not just the first one found, we have
the opportunity to determine the previously-registered command, so that
we can wrap it.
