New Revision: 307150

  Avoid using 'head' in generating groff doc date
  It may not be available in certain cross build cases.
  Note that this is a slight change in functionality, in that now only the
  first line of the source ChangeLog file is processed. This is acceptable
  as groff will be retired and we won't encounter a possibly-different
  ChangeLog format.
