    prop250: Don't use {0} to init static struct -- causes warning on clang.
    
    See ticket #19132 for the clang/llvm warning.
    
    Since voting_schedule is a global static struct, it will be initialized
    to zero even without explicitly initializing it with {0}.
    
    This is what the C spec says:
    
    	If an object that has automatic storage duration is not initialized
    	explicitly, its value is indeterminate. If an object that has static
    	storage duration is not initialized explicitly, then:
    
    	— if it has pointer type, it is initialized to a null pointer;
    	— if it has arithmetic type, it is initialized to (positive or unsigned) zero;
    	— if it is an aggregate, every member is initialized (recursively) according to these rules;
    	— if it is a union, the first named member is initialized (recursively) according to these rules.
