Hi,

the code in src/stdio/__stdout_write.c checks whether output is going to
a terminal and if it's not the case disables line buffering. I'm
wondering what's the reason behind this? This causes some programs to
produce different output depending whether stdout is terminal or not,
not a bit deal, but I don't see much profit in disabling buffering
either.

From the spec <http://pubs.opengroup.org/onlinepubs/009695399/functions/stdin.html>: "the standard input and standard output streams are fully buffered if and only if the stream can be determined not to refer to an interactive device."
