    The operator precedence table is wrong.
    <http://docs.python.org/reference/
    expressions.html#summary>
    shows "in"/"not in" having less priority than
    comparisons like "==", but that's not true:

    py> 2 in (1,2) == True
    False

    The .rst file is wrong, as well as all the
    generated .html files since version 2.1 at least.
    But the original Latex source lists them in the
    same group.

    Looks like the latex->html and latex->rst tools
    both had the same problem with this kind of
    table construct.

    The attached patch is based on the ref5.tex file
    included in Python 2.5
