Comment Actions
Please make the two changes suggested by bz@ and then feel free to commit this. I think its OK to ask re@ to commit this during the freeze. (I also won't be upset if they say "no".)
Note that it is worth adding a sentence to your commit message explaining "why" we want this separate counter.
