    bin/date             date.1 vary.c 
  Log:
  Change the behaviour of `-v' so that, e.g., stepping a month back
  on March 31 won't take you to March 2 or 3 (now the result will
  be the last day of February.)
  
  In general, now stepping by months from the last days of the current
  month A will take you to the very last day of the target month B if
  B is shorter than A.
  
  The previous version would just step to March 31 and rely on mktime(3)
  to correct the date.  Despite its simplicity, such way was counter-intuitive
  to users and caused pain to shell script writers.
