buffer_read_char() can be used in place of buffer_read_string(1) to avoid consuming valuable static buffer space. The delta applier will use this to read variable-length integers one byte at a time. Underneath, it is fgetc(), wrapped so the line_buffer library can maintain its role as gatekeeper of input.
