* (bug 3324) Incorrect use of sizeof (beast <info@dbwatersports.com>)

* (bug 2946) Console scrolling broken (identified by misantropia)
  + Field_VariableSizeDraw contained a hack to ensure the cursor was always
    visible. Unfortunately this interfered with scrolling long lines. Move the
    hack to a different place
  + Removed commented code in the same function
  + Reworked Field_KeyDownEvent to use a switch( ... ) and set edit->scroll in
    every case, thereby avoiding scrolling issues when "Home" or "End" are
    pressed
