Fix bounds check in buffer_append. We're about to append one character to the buffer _and_ put a \0 after it, so we need the buffer to be at least _two_ characters longer than where the current position is. I think this bug would have had a hard time showing up in normal use, but I managed to trigger it by completely messing up a prototype Emscripten preferences implementation, and a good thing too.
