argument is given, the default buffering policy works as follows:
* Binary files are buffered in fixed-size chunks; the size of the buffer
-<<<<<<< HEAD
- is chosen using a heuristic trying to determine the underlying device's
- "block size" and falling back on `io.DEFAULT_BUFFER_SIZE`.
+ is chosen using a heuristic trying to determine the underlying
+ device's "block size" and falling back on `io.DEFAULT_BUFFER_SIZE`.
On many systems, the buffer will typically be 4096 or 8192 bytes long.
-=======
- is max(min(blocksize, 8 MiB), DEFAULT_BUFFER_SIZE) when the device
- block size is available.
- On most systems, the buffer will typically be 128 kilobytes long.

* "Interactive" text files (files for which isatty() returns True)
use line buffering. Other text files use the policy described above
