Function format_config

builtin/config.c:406–471

* Format the configuration key-value pair (`key_`, `value_`) and * append it into strbuf `buf`. Returns a negative value on failure, * 0 on success, 1 on a missing optional value (i.e., telling the * caller to pretend that did not exist). * * Note: 'gently' is currently ignored, but will be implemented in * a future change. */
