Having said that, I do think a higher-level macro that encapulates
the whole thing may not be such a bad idea, i.e. making the above
into
DECLARE_GIT_GETTER(const char *, get_git_dir, git_dir)
and this and others

into
DECLARE_GIT_GETTER(char *, get_object_directory, git_object_dir)
DECLARE_GIT_GETTER(char *, get_index_file, git_index_file)
DECLARE_GIT_GETTER(char *, get_graft_file, git_graft_file)
