Starting in3ac68a93fd, help.o began to depend on builtin/branch.o, builtin/clean.o, and builtin/config.o. 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. For reasons explained in976aaedc(msvc: add a Makefile target to pre-generate the Visual Studio solution, 2019-07-29), some build artifacts we consider non-source files cannot be generated in the Visual Studio environment, and we already have some Makefile tweaks to help Visual Studio to use generated command-list.h header file. Do the same to a new generated file, config-list.h, introduced by this change. Helped-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: Emily Shaffer <emilyshaffer@google.com>
