Tried that, but it solves only the path setting problem. I have other 
code in the "system-wide" init script pointed to by INIT_LUA, and that 
code is executed anyway. I'd like to bypass it completely, i.e. prevent 
its execution.

Moreover I have several builds of lua in my system (one bare-bone 
PUC-5.1.4, one with a customized interpreter, one 5.2beta, plus several 
ones used to start specific standalone tools) when testing one of those 
I always have to wrap the invocation in some .cmd script otherwise 
LUA_INIT gets in the way. The command line option would simplify things 
really A LOT.
