Is this how copyright works? I'm not a layer, but I thought it was
supposed to reflect changes done to given file in a given year.

So we have either the option to:

* not update it at all (as in many kernel sources)
* don't have it listed explicitly (as seen in other kernel sources)
* update it once a year

I personally like to have a simple solution so I don't have to deal with this 
kind of details while doing interesting things. The current "solution"
was to handle the copyright notices year for the whole project as one entity - 
once per year and then ignore it for the rest of the year.

And I would also prefer not to start a discussion about the differences 
between the inalienable German Urheberrecht, pre 1989 anglo-american 
copyright, post 1989 anglo american copyright and other copyright like laws.
