By all means, please be pedantic, I was flat wrong.

And it matches [$ifs]+ which is the other piece I always forget.

That is exactly what I was saying, thank you. That's what I get for
spending the last few days writing in php, sigh.

What I thought smiley was referring to is when the first argument is
inteded to output -n, but doesn't. What I gave obviously puts an extra
space in (I guess I was a bit fuzzy earlier), echo -n $it^$nl works if
$it is not a list. I've never seen this be a problem in practice myself.
