Hi Steeve,
I think this is just fine. Would you like me to add this to mainline?
 
If so, the preferred way is to send a patch. The hacking.txt file describes 
the submission details. Note that our preferred coding style puts braces on a 
line by themself.  Ah, and I'd also need your full name to properly give you 
credit in changelog.

If you have no time for sending a patch, let me know and we'll integrate the 
changes ourself.
