[RCD] Line length for body wrapping

Please apologize this possible silly question, but I'm not a PHP developer. In sendmail.inc, I see the following statement:

// set line length for body wrapping $LINE_LENGTH = $RCMAIL->config->get('line_length', 72);

Do I understand it correctly that RC first reads the setting "$rcmail_config['line_length']" in main.inc.php (which we have set to 76), and only if it does not exist, it will use a default value of 72?

If so, that's good.

And does this statement apply to un-quoted lines only (and only if format_flowed = false), or to both un-quoted and quoted lines?

I just need to know which behaviour for un-quoted and quoted lines is the deliberate one, before I'm creating a senseless ticket in the bugtracker.
