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.
