This is pretty rough but I'd like to see how people feel about this first. I notice we have two places for command classification. One in command-list.txt, one in __git_list_porcelain_commands() in git-completion.bash. People who are following nd/parseopt-completion probably know that I'm try to reduce duplication in this script as much as possible, this is another step towards that. By keeping all information of command-list.txt in git binary, we could provide the porcelain list to git-completion.bash via "git --list-cmds=porcelain", so we don't neeed a separate command classification in git-completion.bash anymore. Because we have all command synopsis as a side effect, we could now support "git help -a --verbose" which prints something like "git help", a command name and a description, but we could do it for _all_ recognized commands. This could help people look for a command even if we don't provide "git appropos". PS. Elsewhere I introduced --list-builtin-cmds, which should become --list-cmds=builtin if this series seems like a good idea to move forward.
