Re: extra newline after putStrLn?

Generally in Hugs, after doing an IO thing, it writes out a newline.
In GHCi, it doesn't. On balance, I think the Hugs way is better, since
in GHC it's easy to get to:

Prelude> putStrLn "foo"
foo
Prelude> putStr "foo"
fooPrelude>

While in Hugs:

Hugs> putStrLn "foo"
foo

Hugs> putStr "foo"
foo
Hugs>

So it's nothing fundamental, just a difference in what to do after
some arbitrary IO.

Thanks, Neil
