HTML::ExtractMain 0.62 had pod saying
If a most relevant block of content is not found,
"extract_main_html" returns undef.
If I'm not mistaken it's actually an empty list rather than undef --
which makes a difference if using extract_main_html() in a list context.
Empty or undef are both reasonable so I would think change the docs to
match the code.
