Use "|" instead of "+" when combine the _IO_LINE_BUF and _IO_UNBUFFERED flags
Both of "_IO_UNBUFFERED" and "_IO_LINE_BUF" are the bit flags, but I find there are some codes looks like "_IO_LINE_BUF+_IO_UNBUFFERED", while some codes are "_IO_LINE_BUF|_IO_UNBUFFERED". I think the former is not good, even though the final result is same.
