Yeah, that's the way I would have prefered to write this as well.
It took me a while to verify that the intent here was not to clear
only part of the struct.  Using sizeof(variable_name) instead of
sizeof(type) is more readable.

But then you get into the thing where the line before uses
sizeof(type)...

Oh well, I've sent both styles and the maintainer can choose.  :)
