    I wonder if this is a real, legitimate and non-pathological case where
    there might be a difference: hex digits embedded in Hebrew text,
    followed by a comma. In modern Hebrew numbers are written with European
    digits LTR embedded in RTL text, and a comma etc following the numeral
    should probably appear to the left of it. I would guess that Israeli
    programmers use hex digits LTR and sometimes embed them in Hebrew text.
    But a comma will probably come out to the right of the hex number if it
    looks like a Latin script word. Look at the following, which each
    consist of three Hebrew letters, space, hex digit, comma, space, three
    Hebrew letters. Well, the bidi algorithm messes them up on my screen, in
    Word 2002 and in Mozilla. But maybe someone can see the difference.

    בצד A, בצד

    But I am not suggesting that this problem is sufficiently serious to
    justify encoding a new set of hex digits.
