There are three possible issues AFAICT:
1) Currently the style element is only allowed within the head element,
per HTML 4.01 Transitional. It's trivial to lift this: just change
the line beginning style in src/definitions/html/elements so that
the fourth field says "%head+%inline" instead of "%head".
I'll make this change for 0.9.2.
2) If a script element is embedded (directly or indirectly) within a body,
and TagSoup is forcing it to be in a bogus head element, that's a bug.
Can someone send me a test case?
3) If a script element is not within either head or body (directly within
the html element or no element at all) then TagSoup has to guess whether
to insert a head or a body element, and currently it guesses head.
I could change this to body, but I'm not sure if that would make things
better or worse on average. Since the parser doesn't look ahead, there's
no way to figure out which is more appropriate in a particular case.

came by, looked over my shoulder and said 'Oh, that happens to me too.
Try hanging up and phoning in again.'" --Beverly Erlebacher
