From: Haaris Mehmood <hsed@xxxxxxxxxxxx> Add --expiry-date as a data-type for config files when 'git config --get' is used. This will return any relative or fixed dates from config files as a timestamp value. This is useful for scripts (e.g. gc.reflogexpire) that work with timestamps so that '2.weeks' can be converted to a format acceptable by those scripts/functions. Following the convention of git_config_pathname(), move the helper function required for this feature from builtin/reflog.c to builtin/config.c where other similar functions exist (e.g. for --bool or --path), and match the order of parameters with other functions (i.e. output pointer as first parameter).
