To facilitate testing and verification of the requests sent by git-fetch
to the remote side we permit logging the received packet lines to file
descriptor 3 if GIT_DEBUG_SEND_PACK has been set. Special start and
end lines are included to indicate the start and end of each connection.
$ GIT_DEBUG_SEND_PACK=1 git fetch 3>UPLOAD_LOG
$ cat UPLOAD_LOG

>From the above trace the first connection opened by git-fetch was to
download two refs (with values 8e and dd) and the second connection
was opened to automatically follow an annotated tag (32).
