bifurcated copyright for etc/*.tex files

[Thien-Thi Nguyen]

for the etc/*.tex files, i would like to update the copyright
notice in the comments w/ the full list of years, and the
rendered copyright notice w/ 2005, only.  for example:

  % Copyright (C) 1997, 2002, 2003, 2004, 2005 FSF, Inc.
  ...
  \def\year{2005}

the rationale is that for reference cards and such, a big (and
ever-increasing) list of years is unnecessary clutter.

what do you think of this (idea A)?

another approach is to allow sequence-compression in the
rendered notice, while keeping the comment fully expanded,
like so:

  % Copyright (C) 1997, 2002, 2003, 2004, 2005 FSF, Inc.
  ...
  \def\year{1997, 2002--2005}

what do you think of this (idea B)?
