[Zope] Is there a <dtml-comma> for SQL UPDATEs?

[Chris McDonough]

Hmmm.... AFAIK, there's no such animal as <dtml-comma>.  But without
much research on the matter, I'd say that this'd do it:

UPDATE
  users
SET
  <dtml-sqlgroup>
    <dtml-sqltest login type=nb optional>
    <dtml-if email>,<dtml-sqltest email type=nb optional></dtml-if>
  </dtml-sqlgroup>
WHERE
  <dtml-sqltest userid type=int>
