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.
