2450 # will use it. (This is not the normal case.)

2454 # 1. Collect all relevant .orig from parent directory

2456 # debian/{patches,rules,source/format}

2459 # 4. Extract the fake .dsc
2460 # Now the fake .dsc has a .pc directory.
2461 # (In fact we do this in every case, because in future we will
2462 # want to search for a good base commit for generating patches.)

2465 # 1. Make a new working tree with the same object
2466 # store as our main tree and check out the main
2468 # 2. Copy .pc from the fake's extraction, if necessary
2469 # 3. Run dpkg-source --commit
2470 # 4. If the result has changes to debian/, then
2471 # - git-add them them
2472 # - git-add .pc if we had a .pc in-tree
