Merge branch 'jk/repack-pack-keep-objects'

Recent updates to "git repack" started to duplicate objects that
are in packfiles marked with .keep flag into the new packfile by
mistake.

* jk/repack-pack-keep-objects:
repack: s/write_bitmap/&s/ in code
repack: respect pack.writebitmaps
repack: do not accidentally pack kept objects by default
