This blurs the lines a bit between what the generic istream_source() is responsible for, versus the type-specific helpers. I think that works a bit against the original design, which was trying to be very abstract and polymorphic. But that doesn't seem to have bought us much. Just considering the whole set of streaming code as a module with helper functions is a bit simpler and more usual for our codebase. So I'm OK with it unless Junio (as the original author) has strong objections. -Peff
