Document raw html inline element better

[jidanni]

pandoc man page says:

And the following produces a raw html inline element:

This is `<a>html</a>`{=html}

OK, but to hammer home what you mean, I would add:

See:
$ echo 'This is `<a>html</a>`' | pandoc
<p>This is <code>&lt;a&gt;html&lt;/a&gt;</code></p>
$ echo 'This is `<a>html</a>`{=html}' | pandoc
<p>This is <a>html</a></p>

(Though it might be hard to put on the man page unscathed.)

By the way, please don't use the name <a>html</a> here, use <a>Nerblestien</a>, etc. Else it is too confusing also.
