Bump copyrights

[ariel-anieli]

$ git grep -nPi copyright \
      | perl -nE 'print if /copyright/i && /\d{4}/' \
      | awk -F: '{print $1}' \
      | xargs -I {} sh -c 'year=`date +"%Y"`;
                           sed -i -e "/[Cc]opyright/s/\-[[:digit:]]\{4\}/-${year}/; \
			   /[Cc]opyright/s/ [[:digit:]]\{4\}\( \|,\)/ ${year}\1/" {}'

I don't think we actually need to update those? Anyway, copyright rules are generally "life of the author" + 20-70 years in countries signing the Berne convention; an older notice isn't actually changing how long your copyright lasts, and older might be better.

Your explanation makes sense; thanks for having mentioned that convention. I didn't know about it.
