Is your feature request related to a problem? Please describe.
"I'm always frustrated when [...]" I need to write:

<code><dfn>thing<dfn></code>

Describe the solution you'd like

I'd like to:

<dfn>`thing`</dfn>

And then have ReSpec automatically put code on [=thing=], so if the dfn's only child is code, then the [=thing=] should automatically be "code" too.
