Replace wrongly deleted header banner, fix formatting

I reviewed the diff hunks of 05da2fe52162c80dfa that don't contain
'#include' lines, and found two unintended changes. I deleted a header
banner inadvertently while inserting a header, and changed the
indentation of a constructor in an odd way. Add back the banner, and
reformat the constructor.
