[imp] Messsages sort order

[Sylvain Fauvel]

	Hello,

	I did change the sort direction in imp/config/prefs.php as follows
	    (value was 0, i set it to 1).

		// user preferred sorting direction
		$_prefs['sortdir'] = array(
		    'value' => 1,
		    'locked' => false,
		    'shared' => false,
		    'type' => 'enum',
		    'enum' => array(0 => _("Ascending"),
		                    1 => _("Descending")),
		    'desc' => _("Default sorting direction:")
		);


	Messages in the inbox are still sorted in ascending order if i use the
	POP protocol but in descending order if i use the IMAP protocol.

	Also, when i change the sort order interactively while using IMP,
	it takes several attempt to finally get the reverse order.
