There are two major changes here: adding short options to the usage and the "simplification" of the usage function. The short options should be added in the patch that made them available, not here. The other changes need some sort of justification. It's not obvious to me that this is simpler. Sure usage itself is a bit simpler, but now parse_opts has to worry about calling cleanup and exit. Other patches in this set similarly lack justification: using atexit and EXIT_SUCCESS/EXIT_FAILURE and limiting parse_opts to command-line options.
