I guess not all files changed in 2006 need their copyright updated.
For example, it would be good to remove trailing whitespace from all
files just before the release.  Updating copyright is not needed
after such change.

A good interface for mass-replacing is query-replace.  You can just do

M-x find-dired RET -name '*.el' RET t Q

and use a function call like  \,(copyright-fix-years \0)
in the replacement part.
