Yes, though we do we even need to store the bit?

If we just check file_exists() in the second loop, then this is entirely
local to update_server_info(). And other users of packed_git do not have
to wonder who is responsible for setting that flag in the global list.
It does mean you'd over-allocate the array (and num_pack would have to
be adjusted down to "i" after the second loop), but that's not a big
deal. I do think the whole two-loop thing would be more readable if we
simply grew it on the fly with ALLOC_GROW().
