<h1> vs. <h2>

[Karl Berry]

Hi Patrice -- I'm sorry, but I can't remember if we discussed this
already.  tp generates <h1> for @unnumbered, etc.  C makeinfo generates
<h2>.  I find <h1> awfully loud.  Also, it seems like <h1>
would be the overall document title, so <h2> for chapter-level things
doesn't seem logically wrong.  Did we intentionally choose to switch to
<h1>?

Thanks,
Karl
