The Zope 2.9 behavior is correct.
The ZPT references says for "even": true for even-indexed repetions...so for the first iteration which is the zero-th repetition 'even' is correct.

While fixing http://www.zope.org/Collectors/Zope/2141, I realized that Zope 2.9 behaves "oddly" (pun intended!) regarding odd/even. Take the following ZPT snippet:

<html>
  <body>
    <ol tal:define="results python:range(5)">
      <tal:block tal:repeat="fudge results">
        <li tal:define="odd repeat/fudge/odd"
            tal:content="python:odd and 'odd' or 'even'">Content</li>
      </tal:block>
    </ol>
  </body>
</html>

In Zope 2.9, this will yield:

   1. even
   2. odd
   3. even
   4. odd
   5. even

I find that certainly weird. Zope 3 (and hence Zope 2.10+) produce:

   1. odd
   2. even
   3. odd
   4. even
   5. odd

I guess we'll have to decide whether this is a bug or feature in Zope 2.9, and hence either adjust Zope 2.10 to match Zope 2.9's behaviour or fix Zope 2.9.
