I'm getting some really unexpected rtrim behaviour, which I believe is a bug.

echo 'X' . rtrim('foo bar ') . 'X';

this gives 'Xfoo barX' as one would expect.

echo 'X' . rtrim('foo bar ', ' ') . 'X';

this gives 'XX' as the result.

i'm using php-4.0.6.  Am I misunderstanding something horribly, or is this
a legitimate bug?
