Applied to master, thanks.

BTW, I just noticed you assigned that patch to me as author, and I'm not
sure why (yeah, I provided the blurb, but you applied it and tested it
and submitted it). Anyway, too late now.

Thanks! :-)

Regards,
Yann E. MORIN.

Hi Yann,

doing copy'n'paste I would not call authorship. It was your intellectual 
work which I used to cook up this patch, so for me it was obvious that 
you are the author ;)
