  #1194222: make parsedate always return RFC2822 four character years.

  Two character years are now converted to four character years using
  the Posix standard rule (<68 == 2000, >=68==1900).  This makes the
  parsed date RFC2822 compliant even if the input is not.

  Patch and test by Jeffrey Finkelstein.
