The short option -h is hard-wired in parseopt to list the options of a command together with a short explanation. If -h is to be given a different meaning then the flag PARSE_OPT_NO_INTERNAL_HELP has to be specified, which turns off handling for -h, --help and --help-all (except that --help handling is effectively overridden by git.c, but that's a different story).
Most commands that do that, grep and show-ref in particular, still show the usage when -h is specified as the only parameter and with --help-all by implementing explicit handlers for them. This series makes it easier for them by letting them override -h handling without any flag.
