In 5.1 the "..." will be itself an expression that results in the
variable arguments of a vararg function. So, the equivalent of
<<unpack(arg)>> will be simply "...". If you really want a table
with all parameters, you can collect them with <<{...}>>.

To keep compatibility, a vararg function that does not use any "..."
will still build its arg parameter.
