* When reading from the console on Windows in `ICANON` mode, the

|
* returned line will end with `\r\n` rather than `\n`.
|
|
*
|
|
* @param stream specifies non-null open input stream
|
|
* @param len optionally receives byte length of line
|
|
* @return nul-terminated line string, including the `\n` character
|
|
* unless a line happened before EOF without `\n`, otherwise it
|
|
* returns `NULL` and feof() and ferror() can examine the state
|
