From the manual (Lua 5.2): "Vararg expressions, denoted by three dots
('...'), can only be used when directly inside a vararg function; they
are explained in §3.4.10." and "Before starting to run the script, lua
collects all arguments in the command line in a global table called
arg." and "it can also access these arguments with the vararg
expression '...'."
Unfortunately, the latter "also access"part doesn't work in the case
you are showing as I have no way to assign something to the vararg
expression (without wrapping the chunk into a function, but this
creates some other issues).
So, it may deem to be a bug that I can't do much about. If you use
"arg" instead of {...}, you should get the same result in both cases.
Paul.
