repack: document --unpack-unreachable option
This was added back in 7e52f56 (gc: do not explode objects which will be immediately pruned, 2012-04-07), but not documented at the time, since it was an internal detail between git-gc and git-repack. However, as people with complicated setups may want to effectively reimplement the steps of git-gc themselves, it is nice for us to document these interfaces.
