2452 # 4. Extract the fake .dsc
2453 # Now the fake .dsc has a .pc directory.
2454 # (In fact we do this in every case, because in future we will
2455 # want to search for a good base commit for generating patches.)

2458 # 1. Make a new working tree with the same object
2459 # store as our main tree and check out the main
2461 # 2. Copy .pc from the fake's extraction, if necessary

2465 # - git-add .pc if we had a .pc in-tree
