OK millert@ if you fix the whitespace (should use tabs for indent

systat is not flushing output

[Solene Rapenne]

I wanted to use systat -b -d 10 iostat 1 | something to parse output in
real time but it was not possible, systat doesn't flush output.

otto@ suggested this change, I tried it and it works.

This flush output at the end of writing a page in raw mode (-B or -b
flags).

ok?
