	** Fix for bug #211267

	* addressbook/printing/e-contact-print.c: (struct _EContactPrintContext),
	(e_contact_print_letter_heading), (e_contact_start_new_page),
	(e_contact_print_contact), (contact_draw_page),
	(e_contact_print): Report correct number of pages to print
	and print them as requested.

	* calendar/gui/print.c: (bound_text), (print_attendees), (print_day_event),
	(print_todo_details), (print_comp_draw_real), (print_comp_draw_page),
	(print_comp_begin_print), (print_comp): When printing only one event,
	then divide it to more pages if required, also word-wrap description
	text if necessary to fit the page.
