This meant that help.o was unusable outside of the context of the main Git executable. To make help.o usable by other commands again, move list_config_help() into builtin/help.c (where it makes sense to assume other builtin libraries are present). When command-list.h is included but a member is not used, we start to hear a compiler warning. Since the config list is generated in a fairly different way than the command list, and since commands and config options are semantically different, move the config list into its own header and move the generator into its own script and build rule.
