Since I'm not using this in the if-condition above, I'm not sure if this check
is of any value.  It disables a bit of code in a case where it's not apparently

I would vote for revert since it is not needed for this CL.

Done.

This variable doesn't appear to be used anywhere.

Let's remove it then.
