## Footnotes
TODO: proper spec.
This test is based on the one from gfm.
```````````````````````````````` example
This is some text![^1]. Other text.[^footnote].
Here's a thing[^other-note].
And another thing[^codeblock-note].
This doesn't have a referent[^nope].
[^1]: Some *bolded* footnote definition.
[^footnote]:
> Blockquotes can be in a footnote.
as well as code blocks
or, naturally, simple paragraphs.
[^other-note]: no code block here (spaces are stripped away)
[^codeblock-note]:
this is now a code block (8 spaces indentation)

````````````````````````````````
Ensure that nested blocks in footnotes are rendered in the
right order (#63).
```````````````````````````````` example
Hello[^test]
Footnote containing a list[^list]
[^test]:
> first
>
> second
>
> third
[^list]:
1. First element
1. Second element
.
<p>Hello<sup class="footnote-ref"><a href="#fn-test" id="fnref-test">1</a></sup></p>
<p>Footnote containing a list<sup class="footnote-ref"><a href="#fn-list" id="fnref-list">2</a></sup></p>
<section class="footnotes">
<div class="footnote" id="fn-test">
<div class="footnote-number">
<a href="#fnref-test">1</a>
</div>
<div class="footnote-contents">
<blockquote>
<p>first</p>
<p>second</p>
<p>third</p>
</blockquote>
</div>
</div>
<div class="footnote" id="fn-list">

<li>First element</li>
<li>Second element</li>

````````````````````````````````
Footnote labels cannot be empty, or composed only of whitespace.
```````````````````````````````` example
Test [^] link [^ ]
[^]: https://haskell.org
.
<p>Test <a href="https://haskell.org">^</a> link <a href="https://haskell.org">^ </a></p>
````````````````````````````````
```````````````````````````````` example
[^]: not a footnote
[^ ]: not a footnote
[^
]: not a footnote
.
<p>[^]: not a footnote</p>
<p>[^ ]: not a footnote</p>
<p>[^
]: not a footnote</p>
````````````````````````````````
Footnote labels cannot contain line breaks, even where link labels can.
```````````````````````````````` example
[^foo\
bar]: not a footnote definition
[baz\
quux]: https://haskell.org
[first
second]: https://haskell.org
[^third
fourth]: not a footnote definition
[baz\
quux]
[^foo\
bar]
[first
second]
[^third
fourth]
.
<p>[^foo<br />
bar]: not a footnote definition</p>
<p>[^third
fourth]: not a footnote definition</p>
<p><a href="https://haskell.org">baz<br />
quux</a>
[^foo<br />
bar]
<a href="https://haskell.org">first
second</a>
[^third
fourth]</p>
````````````````````````````````
Paragraphs in footnotes can be lazily wrapped (#126).
```````````````````````````````` example
[^foo]:bar
baz
[^foo]
.
<p><sup class="footnote-ref"><a href="#fn-foo" id="fnref-foo">1</a></sup></p>
<section class="footnotes">
<div class="footnote" id="fn-foo">
<div class="footnote-number">
<a href="#fnref-foo">1</a>
</div>
<div class="footnote-contents">
<p>bar
baz</p>
</div>
</div>
</section>
