sys.stdin.readline() in Windows console only allows 512 characters on input per line. So large pastes are truncated at 512 chars, which is a bit inconvenient for prototyping.

The buffer size seems to be determined by BUFSIZ compile time constant:
https://github.com/python/cpython/blob/63298930fb531ba2bb4f23bc3b915dbf1e17e9e1/Modules/_io/winconsoleio.c#L30-L31

In C, I am able to set a larger buffer at runtime with setvbuf() call:
setvbuf(stdin, NULL, 0, 2024);

But I can't seem to make it work through ctypes.cdll.msvcrt.setvbuf
