Why is this important? What is the problem that it is trying to solve?

I know that our functions are not expecting the temp var to be NULL. IOW,
whenever we have a 'const char **foo' function, where foo is a return value,
then the function typically doesn't care what the input value is. Does one
of the SVN functions actually require the initialization?
