Handling nested =open directives

Hello Pod People,

Given the following erroneous POD, should the formatter interpret the bold
line as the start of a text paragraph and indent it (and therefore each line
afterwards would also be treated as a text paragraph), or should the
formatter keep the bold line at the same indent level as the prior
italicized line, and treat the "=item *" as a bulleted list instead of a
text paragraph?

I believe that it should treat it as the former because the bold line is
after the nested =open, but the test case for htmlview.pod disagrees -- it
treats it as the latter.

Thank you,
Marc
