I thought of that, but for the time being decided against. Main reason
was that external tools can't easily distinguish between a non-zero code
that means "lua has a problem with my script" (i.e. lua error status<>0)
vs "my script has a problem with whatever" (i.e. my error code<>0). And
whatever I do, I can construct cases where doing the opposite would be
better.

(Anyway, Lua is not supposed to have problems with my scripts...;-)
