Can you please explain the purpose of those changes ? Do you use some 
tools that get disturbed by such cosmetic errors ? Otherwise what is 
your reason ?

We don't accept such standelone minor cosmetic changes at the first 
place because it looks like a waste of time.

If you have major reasons to want those changes, please re-submit with a 
details explanation in the commit message.

Thanks
Christophe
