The improvements look good to me.

This patch was severely whitespaced damaged, probably due to:

  Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes

in the original, so I am resending an unmangled version for Junio's
convenience. Chris, please make sure to turn off flowed text when
sending future patches.

Thanks, both.

Hmph - sorry about that. I did read SubmittingPatches carefully, but I  
guess Apple Mail tripped me up.

Thanks
Chris
