passing on multiple return values

["David McClurg" <dmcclurg@...>]

i didn't realize multiple return values could be passed on to another
function without a table.

> function foo(x,y,z) print("x=",x,"y=",y,"z=",z) end
> function getpos() return 1,2,3 end
> foo(getpos())
x=      1       y=      2       z=      3

nice.  lua is full of surprises.  :)
