to _IO_buf_base, though not necessarily if we have switched from
get mode to put mode. (The reason is to maintain the invariant
that _IO_read_end corresponds to the external file position.)

+ _IO_write_base is non-NULL and usually equal to _IO_buf_base.
We also have _IO_write_end == _IO_buf_end, but only in fully buffered mode.
The un-flushed character are those between _IO_write_base and _IO_write_ptr.
