Previously, I used a shell script to extract modification date ranges from the Git history, but that was complicated and unreliable, so now every file just gets the same year range in its copyright header. If someone needs to know when a specific file was modified and by whom, they can look at the Git history themselves; no need to include it redundantly in the header.
