Thanks for the info! I got that comment wrong then.

Ouch! This seems like a bug then!

BTW I think that the comment in luaconf.h should be adjusted to be 
clearer in that respect, e.g. (emphasis mine on the suggested mods):

"In Windows, any exclamation mark ('!') in the path is replaced *(by 
Lua) with* the path of the directory of the executable file of the 
current process."

instead of:

"In Windows, any exclamation mark ('!') in the path is replaced by the
path of the directory of the executable file of the current process."
