D6171: crecord: draw on the whole screen

REVISION SUMMARY
  When starting crecord, one can see that it has a small gap on the rightmost
  column which doesn't get used. This is in contrast to other interactive curses
  frontends such as chistedit.
  
  Disabling the displaying of the cursor allows drawing on the whole availabe
  area and thus some hacky code in align() could be removed.
