This is true in some versions of POSIX but not others. It is a
contentious and murky area. If memory serves, fflushing an input
stream had defined behavior in POSIX 1988, then it became undefined,
and now (or soon?) it is becoming defined again.
Anyway it doesn't hurt in practice to fflush and then fseek the input
stream, and in some cases it helps, so the change seems worthwhile.
