Copyright year updates:

    vi $(git whatchanged --since=2013-01-01 | grep '^:100' | sed 's/^[^M]*M//' | sort -u | fgrep -v test/)

Did 2014 first, since otherwise every file I touched to update to 2013
would show as changed in 2014.  Last invocation logged to git was during
2012.  Will need to be more careful if auditing next year.
