Comment 2 for bug 433852

Your patch looks good, thanks for fixing this and thanks for the test. I made a few minor style comments in irc which you've fixed.

(I suggested moving the import of removeSecurityProxy to the module globals, but Salgado provided a good rationale for why we shouldn't do that)

s/_context_view/_naked_context_view

split the return into multiple lines, such as:

    has_major_heading = IMajorHeading.providedBy(self._naked_context_view)
    return len(self.items) > 1 and not has_major_heading
