I can't see why there is such a requirement. Even if @w{..}
is implemented as the same <span ..>, <span ..> may be nested
right.

Looks good.

I have the choice to do that when closing the @code or when processing
the text within @code. I think that it is better to do it when processing
text within @code. Indeed, when a @code is closed, what is within
is already html. So if there is an attribute with a - things will be 
messed up, for example an @anchor in @code.

So, if it is done when processing text, it means that @-commands will
stop the word detection, so that, for example

@code{it is aa-bb@'{e}cc_d}

will lead to

<code>it is <span class="nocodebreak">aa-bb</span>&eacute;<span 
class="nocodebreak">cc_d</span>

I don't think we should worry about that, though.
