Leading digits are replaced with the new indexes, and a subsequent '_' is replaced with a '-'. If 'sed_re' is given, it is interpreted as a valid sed expression, and is be applied to the patch name. If the environment variable FAKE is set to 'y', then nothing gets done, the command to run is only be printed, and not executed (so you can check beforehand). 'dst_dir' must not yet exist.
