-/**
- * Include Directives
- * ------------------
- *
- * By default, the config parser does not respect include directives.
- * However, a caller can use the special `git_config_include` wrapper
- * callback to support them. To do so, you simply wrap your "real" callback
- * function and data pointer in a `struct config_include_data`, and pass
- * the wrapper to the regular config-reading functions. For example:
- *
- * -------------------------------------------
- * int read_file_with_include(const char *file, config_fn_t fn, void *data)
- * {
- * struct config_include_data inc = CONFIG_INCLUDE_INIT;
- * inc.fn = fn;
- * inc.data = data;
- * return git_config_from_file(git_config_include, file, &inc);
- * }
- * -------------------------------------------
- *
- * `git_config` respects includes automatically. The lower-level
- * `git_config_from_file` does not.
- *
