 Display) seem to work well for simple features, but as soon as I use tools
 like split line or similar, the results of undo and redo become somewhat
 arbitrary (at least to the innocent user).

 Much better, thanks !

 There still is some confusion when one goes back one or two steps, then
 digitizes something else. When you then undo and redo again, the stack
 seems to be mixed between the different paths, sometimes leading to
 objects left on screen even when going all the way back to the last
 possible undo.

 You can check a [http://tomahawk.ulb.ac.be/moritz/wxdigit_undo_redo3.ogv
 short example screencast] and a
