* undo_funcs.h: Removed setCursorParUndo to simplify things a bit. Renamed setUndo family to recordUndo. Renamed FINISH to ATOMIC which I think is a bit clearer. EDIT is gone, since it was premature optimisation, and broken for mathed anyway. * undo_funcs.C (performUndoOrRedo): Cleaned up and made it work with cursor positioning in insets as well (math insets still do not work, but that's a different story anyway.) It mysteriously crashes sometimes with undo in the first paragraph, but I'm fairly confident that this is a compiler bug. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@7358 a592a061-630c-0410-9148-cb99ea01b6c8
