interesting tidbit in store_repl_heap.cc

[Kinkie]

It's been there forever, and a build with the most recent clang
version is failing on it:

store_repl_heap.cc:224
try_again:

    if (!heap_nodes(h->theHeap) > 0)

Does anyone have any idea about what this code is supposed to do? A
cursory look at the code would replace it with
   if (heap_empty(h->theHeap))

but before doing that I'd like to make sure I didn't misunderstand.

Thanks
