[Zope] verify file data field

[Jens Vagelpohl]

you're right, it doesn't care if it is empty because zope will always
construct a FileUpload object. so the test <dtml-if
"_.getitem(REQUEST['file']"> will always return "true" because
REQUEST['file'] will return the FileUpload object.

what you're looking for can be done by asking for the name that was put into
the input field. if that name is empty there was no upload. something like:

<dtml-if expr="REQUEST['file'].filename != ''">
  we have a file
</dtml-if>
