I'll drop " = NULL", as it is our convention to let BSS take care of
the zero initialization for global variables as much as possible.

Other than that, I did not see anything objectionable in this round,

Dscho mentioned--I do not have a strong preference either way, so
I'll queue it (at least tentatively) on 'pu'.
