We usually call specifier_printf() and then check the validity of the result. In many cases, validity checkers, e.g. path_is_valid(), refuse too long strings. This makes specifier_printf() refuse such long results earlier. Moreover, unit_full_string() and description field in sysuser now refuse results longer than LONG_LINE_MAX. config_parse() already refuses the line longer than LONG_LINE_MAX. Hence, it should be ok to set the same value as the maximum length of the resolved string.
