Separator for inline fields doesn't display

Sadly i can't find the other issue but i'm 100% convinced that there was an issue about this bug already.

I also confirm, not related to CCK. I had 4 fields, and made the 2 in the middle inline fields with a '|' as a separator. It doesn't get rendered. In some of the rows, the first field is empty (might be causing this?). Since the second field is always there, I'll put the separator inside the first, as a workaround.

Issue names on views issue queue are not representative, so it's really hard to find stuff. =/

In theme.inc's function template_preprocess_views_view_fields() is responsible for setting the separator:

if (!empty($vars['options']['separator']) && $inline && $object->inline && $object->content) {
  $object->separator = filter_xss_admin($vars['options']['separator']);
}

But if the object's content is empty and also if it is the string '0' the separator won't be set. I am not sure, why $object->content is checket here but I guess it should be enough to check isset($object->content). Because also if it is an empty string there should be a separator, because an empty field could for example have a label. If you hide empty fields, than there won't be an $object variable and so no separator. Therefore I guess we can also omit the check for isset($object->content). But on the last assumption I am not sure, so I created the patch with isset - for views-6.x-2.x-dev and views-6.x-3.x-dev.
