commit dcd60be19f9298fa20f3d0f3efcdb8b9f78e924b

    tmac/an-ext.tmac: Refactor.
    
    * tmac/an-ext.tmac: Refactor.  Rename `mX` to `mZ` so we can use `mX`
      for an "in-example" state register in a future commit.  Rename `mE` to
      `mF` to store the current font's mounting position.  Bizarrely, `mF`
      was not already used for this purpose.
