This may be okay for flushing input but if you want to process it, then
having the test for EOF and NL at the bottom is wasteful as the code
within the DO clause has to do the test anyway.

A reasonable compiler will optimise that if you could. Even if it
doesn't, clarity is usually much more important than that kind of
micro-optimisation.
