2358 # will use it. (This is not the normal case.)

2364 # debian/{patches,rules,source/format}

2367 # 4. Extract the fake .dsc
2368 # Now the fake .dsc has a .pc directory.
2369 # (In fact we do this in every case, because in future we will
2370 # want to search for a good base commit for generating patches.)

2373 # 1. Make a new working tree with the same object
2374 # store as our main tree and check out the main
2376 # 2. Copy .pc from the fake's extraction, if necessary
2377 # 3. Run dpkg-source --commit
2378 # 4. If the result has changes to debian/, then
2379 # - git-add them them
2380 # - git-add .pc if we had a .pc in-tree
