Fixes the GUI part of bug #7892.

2001-09-26  Federico Mena Quintero  <federico@ximian.com>

	Fixes the GUI part of bug #7892.

	* gui/dialogs/alarm-page.c (get_alarm_duration_string): Return
	NULL if the duration is zero.
	(get_alarm_string): Handle duration of zero.  Also, hopefully
	make the strings be more l10n-friendly.

	* gui/alarm-notify/alarm.c (alarm_ready_cb): I am a moron.  Fix
	reversed test.
