 automatically modified from the form they are digitized in because of
 overlaps, the second original feature causing the overlap seems to be
 erased from the undo stack, meaning that it remains, even if you undo all
 the way to origin or if you close without saving.

 line. The lines are correctly split at the intersection. If you then undo
 the second line remains in its original (unsplit) form. The same is true
 for two overlapping polygons or a line crossing a polygon.

 Fixed in r63349,50 (trunk, relbr70), please test.

 If you need more explanation, I can write some, but right now I have to
 go.
