Most of these are trivial and do not deserve copyright. I was unaware of 
these exceptions.

I believe the following copyright should be added:
Ludo 2015 for cb151c68bf and 222e3319bd

Neither of those two changes are greater than 10 lines but I'd call them 
non-trivial.

Feel free to close this bug after you've decided if you'll add that one 
copyright. Had I known what I know now I wouldn't have opened this bug.

Thanks,

Morgan
