Havoc Pennington 310a0d4fcc Handle chopping off \r\n and 0x2029 in addition to \n before passing to
2000-12-11  Havoc Pennington  <hp@redhat.com>

	* gtk/gtktextlayout.c (gtk_text_layout_get_line_display):
	Handle chopping off \r\n and 0x2029 in addition to \n before
	passing to PangoLayout

	* gtk/gtkimcontextsimple.c
	(gtk_im_context_simple_get_preedit_string):
	return an empty string if no match is pending

	* gtk/gtkimcontext.c (gtk_im_context_get_preedit_string): add
	assertion that the returned preedit string was sane

	* gtk/gtktext*.[hc], gtk/testtext.c, gtk/testtextbuffer.c:
