I think at least Rich would not add checks for NULL in functions
that don't expect to be called with NULL, but on the other hand
moves the NULL check into the free() calls. But in that case, we
also clearly document that it can be called with NULL.

So it's at least not general that there shouldn't be a NULL check.
