Comment(by stevage):

 I had a bit of a look. It's not entirely obvious what the correct
 behaviour is when pressing "undo" in the middle of a draw sequence. A few
 possibilities:
 1) Undo should be like delete/minus, except creating "redo" actions rather
 than "undo" ones.
 2) Undo should be exactly like delete/minus (ok, that would be weird)
 3) Undo should instantly remove the whole drawn way.
 4) Nothing - disable. (Not as bizarre as it sounds, various other editing
 programs work this way.)

 There's also two choices about how the whole undo/redo thing works for
 drawn nodes:
 1) Individual nodes can be undone/redone
 2) The whole sequence (between starting drawing and pressing
 enter/finishing) is one undo step.
