	* app/fileops.c: make the file_save dialog sensitive again if the
	user clicked "No" when asked if he wishes to overwrite a file.

	* app/gimpimage.c: when saving an undoable parasite, just do it
	without calling undo_push_cantundo(). Undoable parasites are used
	by many save plug-ins to attach a comment, but this operation
	shouldn't prevent the user from using the undo_stack afterwards.
	The JPEG plug-in has an additional bug that I couldn't solve, so
	undoing after a Save As JPEG is still impossible.

	* app/undo_history.c: lame attempt to draw the clean symbol at the
	correct undo step. Not perfect but much better as before...
