app/tools/gimpiscissorstool.h Added some status bar messages. Use 

2007-01-19  Raphael Quinet  <raphael@gimp.org>

	* app/tools/gimpiscissorstool.h
	* app/tools/gimpiscissorstool.c: Added some status bar messages.
	Use ISCISSORS_OP_CONNECT to let the user know when the cursor is
	above the first point and the user can connect and close the
	curve.  Allow the user to press Enter or Escape to confirm the
	selection or cancel the tool.  Fixes bug #398309.
