Let me try to explain it better. In your former example you had two levels
of argument checking: the one in your code (process-command-args) and the
one performed again by si:top-level. That was the reason why redefining
locally *help-file* did not work.

In the new version si:top-level does not invoke process-command-args. The
only argument processing will happen at the beginning. If you wish to signal
an error due to missing or wrong arguments, then you have to customize the
value that you give to  process-command-args.

Alternatively, if all the arguments you need are ECL's, then invoke
(SI:TOP-LEVEL T) instead of (SI:TOP-LEVEL).
