[PATCH 2/2] pack-objects: report actual number of threads to be used

In the case of a small repository, pack-objects is smart enough to not start more threads than necessary. However, the output to the user always reports the value of the pack.threads configuration and not the real number of threads to be used. This is easily fixed by moving the printing of the message after we have partitioned our work.

(pack.threads is on autodetect and would be set to 4) $ git-repack -a -d -f Counting objects: 55, done. Delta compression using 2 threads. Compressing objects: 100% (48/48), done. Writing objects: 100% (55/55), done. Total 55 (delta 10), reused 0 (delta 0)
