It seems as if in every case, you just added every year from the first
copyright date to the present. This is not exactly how it is supposed
to work. The idea is, you should add every year where the file was
released with a non-trivial amount of changes in either the file
itself or the "package" (ie Emacs in this case).

Since 2001, Emacs has been publicly available by anon CVS. This
counts as a "release" every year. So any file that was in Emacs 21 (in
2001) should have the years 2001-2006 inclusive added. Files added to
CVS since Emacs 21 should have the years N-2006 added, where N is the
year of addition.

Before 2001, you just need to add the dates of the Emacs releases
(assuming the files were in Emacs at the time). I suspect that few
files have actually had this done in a rigorous fashion. So if I were
you, I probably would just have added the years 2001-2006.

(disclaimer: this is my understanding).

OK (I just found it odd to see files in Emacs which the FSF has no
claim on).
