The test case might be hard to make.
The idea is :
if (size > h->size &&
    h->next->magic == FREE &&
    size < h->size + h->next->size)
{
  h->size += h->next->size + GRUB_MM_ALIGN;
  h->next = h->next->next;
  return h;
}

But should be done smarter, to avoid using a huge free chunk to just
increase the size by, say, 1 byte... I'll do some tests.

Oops, I missed it (again).
