Actually, we need to increase the size of BUFSIZE, not just the size of _buffer. The previous patch might have cause problems if, for instance, state->free_in_buffer was 127 but 129 bytes were compressed. In that case, only 127 of the 129 bytes would have been written to the file. Also document the fix.
