Hi Alexandre,

Markus has been black-listed by several core maintainers already, I
think you're wasting your time arguing. WRT the patch: when
introducing this wrapper, I definitely didn't expect people to send
hundreds of often wrong patches based on coccinelle reports, so I
guess removing the script is correct.
