Hm, this list of commits is not exactly helpful, I'm afraid.

I have to admit that I never tried myself to build a lua based
system, optimizing for minimal size - but I'm surprised by your
results.

Yes, I'm aware of this. But then, it would add another level of
powerful scripting capabilities - and as it was already suggested
before, _replacing_ the standard shell is only one way to use lua -
another would be to use lua as a command that can be started from
the shell when needed - assuming you want to pay the price in terms
of size.
