New REPL help mode display is broken by macros

[gdalle]

Try the following in a Franklin page:

```?
@show
```
Some text

The text appears as a link

[tlienart]

Hmm

julia> fd2html("""
       ```?
       @show
       ```
       some text
       """);

julia> println(ans)
<pre><code class="language-julia-repl">help?> @show
</code></pre>
<div class="julia-help">
<pre><code>@show exs...</code></pre>
<p>Prints one or more expressions, and their results, to <code>stdout</code>, and returns the last result.</p>
<p>See also: <code>show</code>, <a href="@ref man-logging"><code>@info</code>, <code>println</code>.</p>
<h1>Examples</h1>
<pre><code class="language-julia-repl">julia&gt; x &#61; @show 1&#43;2
1 &#43; 2 &#61; 3
3

julia&gt; @show x^2 x/2;
x ^ 2 &#61; 9
x / 2 &#61; 1.5</code></pre>



</div>

<p>some text</p>

Could you share the full markdown of the page in which this appears?

[tlienart]

@gdalle did you guys figure this one and can I close it? or is it still causing troubles?

[gdalle]

My friends can reproduce this. So you're most definitely not my friend 🤣

[gdalle]

Let me cook up an MWE

[gdalle]

For me it works even with this simple page

@def title = "MWE"

```?
@show
```
Some text

If it helps, the link "Some text" points to http://localhost:8000/pages/mwe/@ref%20man-logging

[gdalle]

MWE.txt
This is really an HTML page but GitHub didn't like the format, so rename it before opening

[tlienart]

could you please try the latest commit on master and report if it fixed the issue? (basically the docstring has its own markdown and references which Franklin has to dance around and ignore, here it looks like a regex needed to be a bit more general)

[gdalle]

sure, would you prefer if I switched to Xranklin for good? We had discussed it but I never did it

[tlienart]

you could but you'd be one of the early users and shifting from what you have will take some adjustments (for instance @def ... will work but are now deprecated in favour of +++ ... +++ blocks)

one advantage would be to have the ability to have per-page project which may be useful in your case.

[tlienart]

(I would certainly appreciate your feedback and you battle testing it though!)

[gdalle]

per-page projects would be nice! I'll do that in a bit
