  Modified files:
    usr.bin/tail         forward.c 
  Log:
  Save last displayed file by having the "last" pointer global and save it
  during we show the first file's tail.  Instead of:
  
          tarsier% tail -f 1 2
          ==> 1 <==
          foo
          bar
  
          ==> 2 <==
          bar
          foo
  
          ==> 2 <==
          bar2
          foo2
  
  Now with this change, we have:
  
          tarsier% tail -f 1 2
          ==> 1 <==
          foo
          bar
  
          ==> 2 <==
          bar
          foo
          bar2
          foo2
  
  While I'm there, move a comment to where it should belong to.  Also,
  const'ify the "last" static because we will never need to change the
  contents it points to.
