Well actually the FSF recommendes in the GNU maintainer docs [0] to
update it at the beginning of a year for all files and then be done with
it
By the way I just noticed that emacs has a feaure to update it
automatically on save.
With the GTK version it's at Options -> Customize Emacs -> Top-level
customization group
and then Files -> Before Save Hook -> copyright-update
[0] http://www.gnu.org/prep/maintain/maintain.html#Copyright-Notices
"To update the list of year numbers, add each year in which you have
made nontrivial changes to the package. (Here we assume you're using a
publicly accessible revision control server, so that every revision
installed is also immediately and automatically published.) When you add
the new year, it is not required to keep track of which files have seen
significant changes in the new year and which have not. It is
recommended and simpler to add the new year to all files in the package,
and be done with it for the rest of the year."
