instead of global.

 Along the way, I thought of these possible interface changes that we
 might want to consider before rototilling the internals:
 
-1) To remove globals that don't need to be:

+1) To remove a global:
    Change bufsz to be in-out instead of in, and therefore int * instead of
    int, and use that instead of global msg_count.  There are only 3 call
    sites that use msg_count so it wouldn't take much effort to remove use of
    it.  Of course, all call sites would have to change to provide an int *
    instead of an int.  Some now pass constants.
