I just checked in a change to the <dtml-var> tag that allows the following:

    <dtml-var foo missing>

renders to: ''  when foo is missing
   
    <dtml-var foo missing="x">

renders to "x" when foo is missing.

And allows teh entity reference syntax to work:

    &dtml.missing-foo;

renders to '' when missing.

This should fix most of what we've been seeing and people have been
complaining about :-)
