I think so, because we do this above (quoted to avoid gmail mangling the code):

>  /* Get the caption of the item.  If the caption is not a string,
>     evaluate it to get a string.  If we don't get a string, skip this

>  caption = XCAR (item);

When this function returns 0, we don't append this item to the items
that will be displayed.
