So that we don't lose track of this in the list traffic, could you please submit
this to the Collector as a "Feature with Patch" (bugs/features with patches get
priority treatment)?

  http://classic.zope.org:8080/Collector/Collector/developer_input

Paste the patch into the "Description" field, along with the explanation.

Thanks!

Tres.
