Incorrectly nested blockquotes

$ comrak -e multiline-block-quotes -t commonmark -t xml

>>>>
this block is closed with 5 markers below

>>>>>

auto-closed blocks
>>>>>
>>>>

<blockquote>
<p>this block is closed with 5 markers below</p>
</blockquote>
<p>auto-closed blocks</p>
<blockquote>
<blockquote>
</blockquote>
</blockquote>

> this block is closed with 5 markers below

auto-closed blocks

> >

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE document SYSTEM "CommonMark.dtd">
<document xmlns="http://commonmark.org/xml/1.0">
  <multiline_block_quote>
    <paragraph>
      <text xml:space="preserve">this block is closed with 5 markers below</text>

$ comrak -e multiline-block-quotes -t commonmark -t xml

   >>>>
   first-level blockquote
    >>>
    second-level blockquote
    >>>
   >>>>
   regular paragraph

<blockquote>
<p>first-level blockquote</p>
<blockquote>
<p>second-level blockquote</p>
</blockquote>
</blockquote>
<p>regular paragraph</p>

> first-level blockquote
> 
> > second-level blockquote

regular paragraph

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE document SYSTEM "CommonMark.dtd">
<document xmlns="http://commonmark.org/xml/1.0">
  <multiline_block_quote>
    <paragraph>
      <text xml:space="preserve">first-level blockquote</text>
    </paragraph>

Fours spaces makes it a code block

$ comrak -e multiline-block-quotes -t commonmark -t xml

    >>>
    content
    >>>

<pre class="syntax-highlighting"><code><span class="text plain">&gt;&gt;&gt;
content
&gt;&gt;&gt;
</span></code></pre>

    >>>
    content
    >>>

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE document SYSTEM "CommonMark.dtd">
<document xmlns="http://commonmark.org/xml/1.0">
  <code_block xml:space="preserve">&gt;&gt;&gt;
content
&gt;&gt;&gt;
</code_block>
</document>

Detection of embedded 4 spaces code block starts in the column the blockquote starts, not from the beginning of the line.

$ comrak -e multiline-block-quotes -t commonmark -t xml

  >>>
      code block
  >>>

<blockquote>
<pre class="syntax-highlighting"><code><span class="text plain">code block
</span></code></pre>
</blockquote>

> 
> 
>     code block

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE document SYSTEM "CommonMark.dtd">
<document xmlns="http://commonmark.org/xml/1.0">
  <multiline_block_quote>
    <code_block xml:space="preserve">code block
</code_block>
  </multiline_block_quote>
</document>

$ comrak -e multiline-block-quotes -t commonmark -t xml

   >>>>
   content
    >>>
        code block
    >>>
   >>>>

<blockquote>
<p>content</p>

Closing marker can’t have text on the same line

$ comrak -e multiline-block-quotes -t commonmark -t xml

>>>
foo
>>> arg=123

<blockquote>
<p>foo</p>
<blockquote>
<blockquote>
<blockquote>
<p>arg=123</p>
</blockquote>
</blockquote>
</blockquote>
</blockquote>

> foo
> 
> > > > arg=123

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE document SYSTEM "CommonMark.dtd">
<document xmlns="http://commonmark.org/xml/1.0">
  <multiline_block_quote>
    <paragraph>
      <text xml:space="preserve">foo</text>
    </paragraph>
    <block_quote>
      <block_quote>
        <block_quote>
          <paragraph>
            <text xml:space="preserve">arg=123</text>
          </paragraph>
        </block_quote>
      </block_quote>
    </block_quote>
  </multiline_block_quote>
</document>

Blockquotes self-close at the end of the document

$ comrak -e multiline-block-quotes -t commonmark -t xml

>>>
foo

<blockquote>
<p>foo</p>
</blockquote>

> foo

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE document SYSTEM "CommonMark.dtd">
<document xmlns="http://commonmark.org/xml/1.0">
  <multiline_block_quote>
    <paragraph>
      <text xml:space="preserve">foo</text>
    </paragraph>
  </multiline_block_quote>
</document>

They should terminate paragraphs

$ comrak -e multiline-block-quotes -t commonmark -t xml

blah blah
>>>
content
>>>

<p>blah blah</p>
<blockquote>
<p>content</p>
</blockquote>

blah blah

> content

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE document SYSTEM "CommonMark.dtd">
<document xmlns="http://commonmark.org/xml/1.0">
  <paragraph>
    <text xml:space="preserve">blah blah</text>
  </paragraph>
  <multiline_block_quote>
    <paragraph>
      <text xml:space="preserve">content</text>
    </paragraph>
  </multiline_block_quote>
</document>

They can be nested in lists

$ comrak -e multiline-block-quotes -t commonmark -t xml

 -  >>>
    - foo
    >>>

<ul>
<li>
<blockquote>
<ul>
<li>foo</li>
</ul>
</blockquote>
</li>
</ul>

- > - foo

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE document SYSTEM "CommonMark.dtd">
<document xmlns="http://commonmark.org/xml/1.0">
  <list type="bullet" tight="true">
    <item>
      <multiline_block_quote>
        <list type="bullet" tight="true">
          <item>
            <paragraph>
              <text xml:space="preserve">foo</text>

          </item>
        </list>
      </multiline_block_quote>
