Code with a similar purpose was added in568e0e5701but got lost when some things were moved from ve.Surface to ve.ce.Surface in5012ed10. Initializing the selection at (0,0) was known to cause problems before, and since789d0caf09breaks editing of empty documents: typing in an empty document begins in an inline slug, but SurfaceObserver doesn't notice typing in an inline slug unless the ce.Surface pawns it, which is OK because insertions in slugs are always pawned, but the pawning logic believes the cursor to be at offset 0 where there is no slug (it's at offset 1) and so it doesn't pawn. Bonus: update tests and add descriptions for dm.Surface.change tests Change-Id: Id72314d0fe650dacc7cdb842f5cea2f3bfba5145
