	* gtk/gtktextview.c (gtk_text_view_delete_from_cursor): do
	begin/end user action where appropriate
	(gtk_text_view_commit_handler): add begin/end user action

	* gtk/gtktextbuffer.c: add begin/end user action signals, and
	bracket interactive operations with begin/end user action pair.

	* gtk/gtktextbuffer.h (struct _GtkTextBufferClass): remove
	"interactive" arg from insert_text and delete_text signals.
	Add begin_user_action, end_user_action signals
	(gtk_text_buffer_begin_user_action):
	(gtk_text_buffer_end_user_action): New functions to delimit
	a user-visible action

	* gtk/gtkmarshal.list: update to reflect changes to gtktextbuffer
	signals.
