        $ git clone https://github.com/gitster/git tmpgit2 -v -v -v

Now the same for fetch:

        $ cd tmpgit2
        $ git fetch -v -v -v
        From https://github.com/gitster/git
         = [up to date]      master     -> origin/master
         = [up to date]      ab/hooks   -> origin/ab/hooks
         = [up to date]      ad/bisect-cleanup -> origin/ad/bisect-cleanup
         = [up to date]      ad/bisect-terms -> origin/ad/bisect-terms
        ...
         [a lot more wants, cut]

It is missing the want lines completely. I guess that is not that intentional,
but rather we forgot to add the verbosity option correctly to the
fetch in the transport layer.
Looking at the transport code, I am confused on both how the wants are
printed in the clone
case as well as how they are not printed in the fetch case.

Any hints?

(I could use GIT_TRACE_PACKET as a work around, but it's just a hack.)

Thanks,
Stefan
