Nice catch, the patch looks good to me in general.
You should add a commit message better describing what could go wrong
here and double check the indentation, looks a bit like you used space
instead of tabs.
Additional to that you should send the patch as text and not html mail,
cause that makes it practically impossible to apply.
Regards,
Christian.
