It seems like already applied them... :(
While I certainly appreciate patches beeing applied as soon as possible,
I think there should really be a chance to review them before this happens.
Especially when the changes are non-trivial and someone else has posted
patches addressing the same issues before (other contributers might feel
offended ;) ).
Care to fix these issues ?
Regards,
Frank
