Padding Can Truncate (Done)

In k5, padding was treated as a minimum size for the output string:

  2$"abcde"
 "ab"
  6$"abcde"
 "abcde "

In k6, as in older Ks, padding will produce a string with an exact length, truncating if necessary:

  2$"abcde"
 "ab"
  6$"abcde"
 "abcde "

Is this correct?

   / k4
   6$"abcde"
  "abcde "
   2$"abcde"
  "ab"  

   / k2 
   6$"abcde"
  " abcde"
   2$"abcde"
  "de"
