v0.9.13

• Holding Ins in a large directory no longer skips rows or marks them twice: a rescan that finished while you were moving used to put the cursor back where it had been when the rescan started.
• A directory that changes while it is being read no longer starts a second read on top of the first every 200 ms.
• Shift with a movement key sweeps the mark, the way Total Commander does it: shift+up, shift+down, shift+pgup, shift+pgdn, shift+home and shift+end. The row the sweep starts on decides whether it marks or clears, and a partial page at either edge sweeps to the edge.
