copy: Fix use of compound literal outside its scope

C99 6.5.2.5p6:
> If the compound literal occurs outside the body of a function,
> the object has static storage duration; otherwise, it has automatic
> storage duration associated with the enclosing block.

So, we can't use the address of a compound literal here. Instead,
just set p to NULL, and make the loop conditional on p being non-NULL.

Remarks from Quentin:

I made a cosmetic change to Michael's
original patch and merely pushed the
literal at toplevel.
