Odd shadowing in client_side_reply.cc

Hi all,
   in trunk client_side_reply.cc:357 we define a local "old_rep"
variable, which is shadowed 8 lines later in a nested block, in case
of a not-modified answer, but then referenced again in line 396.
This looks a bit suspicious to me, but I don't have enough knowledge
about how that data-path is supposed to behave to properly understand
and possibly fix it.
Can anyone look into it?

Thanks
