+<p>After a heading (in English typographic style) the paragraph does not have a first-line indent.</p>
+<p>In the couple couple of paragraphs that follow the quotes below, we have manually specified <code>\noindent</code> and <code>\indent</code> respectively. This is to check that the filter doesn’t add its own commands to those.</p>

+<div class="no-first-line-indent-after"></div>
+<p>Manually specified no first line indent.</p>
+<div class="first-line-indent-after"></div>
+<p>Manually specified first line ident.</p>
+<p>We can also check that indent is removed after lists:</p>
+<ul>
+<li>A bullet</li>
+<li>list</li>
+</ul>
+<div class="no-first-line-indent-after"></div>
+<p>And after code blocks:</p>
+<div class="sourceCode" id="cb1"><pre class="sourceCode lua"><code class="sourceCode lua"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a><span class="kw">local</span> variable <span class="op">=</span> <span class="st">&quot;value&quot;</span></span></code></pre></div>
+<div class="no-first-line-indent-after"></div>
+<p>Or horizontal rules.</p>
+<hr />
+<div class="no-first-line-indent-after"></div>
+<p>In this document we added a few custom filter options. The size of first-line indents is 2em instead of the standard 1em. We also added an option to remove indent after tables:</p>
+<table>
+<caption>Demonstration of simple table syntax.</caption>
+<thead>
+<tr class="header">
+<th style="text-align: right;">Right</th>
+<th style="text-align: left;">Left</th>
+<th style="text-align: center;">Center</th>
+<th>Default</th>
+</tr>
+</thead>
+<tbody>
+<tr class="odd">
+<td style="text-align: right;">12</td>
+<td style="text-align: left;">12</td>
+<td style="text-align: center;">12</td>
+<td>12</td>
+</tr>
+<tr class="even">
+<td style="text-align: right;">123</td>
+<td style="text-align: left;">123</td>
+<td style="text-align: center;">123</td>
+<td>123</td>
+</tr>
+<tr class="odd">
+<td style="text-align: right;">1</td>
+<td style="text-align: left;">1</td>
+<td style="text-align: center;">1</td>
+<td>1</td>
+</tr>
+</tbody>
+</table>
+<div class="no-first-line-indent-after"></div>
+<p>So this paragraph’s first line is not indented. And we included custom options <em>not</em> to remove ident after ordered lists and definition lists:</p>
+<dl>
+<dt>Definition</dt>
+<dd>This is a definition block.
+</dd>
+</dl>
+<p>This paragraph is indented.</p>
+<ol type="1">
+<li>An ordered</li>
+<li>list</li>
+</ol>
+<p>This paragraph is indented.</p>
+</body>

+First paragraph. In English-style typography, the first paragraph
+shouldn't have a first-line indent, nor the paragraphs below headers.
+
+This paragraph should start with a first-line indent. But after this
+quote:
+
+\begin{quote}
+Lorem ipsum dolor sit amet, consectetur adipiscing elit.
+\end{quote}
+
+\noindent the paragraph continues, so there should not be a first-line
+indent.
+
+The quote below ends a paragraph:
+
+\begin{quote}

+\end{quote}
+
+\indent This paragraph, then, is genuinely a new paragraph and starts
+with a first-line indent.

+\hypertarget{further-tests}{%

+
+After a heading (in English typographic style) the paragraph does not
+have a first-line indent.
+
+In the couple couple of paragraphs that follow the quotes below, we have
+manually specified \texttt{\textbackslash{}noindent} and
+\texttt{\textbackslash{}indent} respectively. This is to check that the
+filter doesn't add its own commands to those.
+
+\begin{quote}
+Lorem ipsum dolor sit amet, consectetur adipiscing elit.
+\end{quote}
+
+\noindent Manually specified no first line indent.
+
+\indent Manually specified first line ident.
+
+We can also check that indent is removed after lists:
+
+\begin{itemize}
+\tightlist
+\item
+  A bullet
+\item
+  list
+\end{itemize}
+
+\noindent And after code blocks:
+
+\begin{Shaded}
+\begin{Highlighting}[]
+\KeywordTok{local}\NormalTok{ variable }\OperatorTok{=} \StringTok{"value"}
+\end{Highlighting}
+\end{Shaded}
+
+\noindent Or horizontal rules.
+
+\begin{center}\rule{0.5\linewidth}{0.5pt}\end{center}
+
+\noindent In this document we added a few custom filter options. The
+size of first-line indents is 2em instead of the standard 1em. We also
+added an option to remove indent after tables:
+
+\begin{longtable}[]{@{}rlcl@{}}
+\caption{Demonstration of simple table syntax.}\tabularnewline
+\toprule
+Right & Left & Center & Default \\
+\midrule
+\endfirsthead
+\toprule
+Right & Left & Center & Default \\
+\midrule
+\endhead
+12 & 12 & 12 & 12 \\
+123 & 123 & 123 & 123 \\
+1 & 1 & 1 & 1 \\
+\bottomrule
+\end{longtable}
+
+\noindent So this paragraph's first line is not indented. And we
+included custom options \emph{not} to remove ident after ordered lists
+and definition lists:
+
+\begin{description}
+\tightlist
+\item[Definition]
+This is a definition block.
+\end{description}
+
+This paragraph is indented.
+
+\begin{enumerate}
+\def\labelenumi{\arabic{enumi}.}
+\tightlist
+\item
+  An ordered
+\item
+  list
+\end{enumerate}
+
+This paragraph is indented.
+
+\end{document}

+<td>1</td>
+</tr>
+</tbody>
+</table>
+<div class="no-first-line-indent-after"></div>
+<p>So this paragraph’s first line is not indented. And we included custom options <em>not</em> to remove ident after ordered lists and definition lists:</p>

+<thead>
+<tr class="header">
+<th style="text-align: right;">Right</th>

+<td>1</td>
+</tr>
+</tbody>
+</table>
+<div class="no-first-line-indent-after"></div>
+<p>So this paragraph’s first line is not indented. And we included custom options <em>not</em> to remove ident after ordered lists and definition lists:</p>

+\maketitle
+
+This sample tests the filter on a document with a metadata
+header-includes of the MetaList type.
+
+First paragraph. In English-style typography, the first paragraph
+shouldn't have a first-line indent, nor the paragraphs below headers.
+
+This paragraph should start with a first-line indent. But after this
+quote:
+
+\begin{quote}
+Lorem ipsum dolor sit amet, consectetur adipiscing elit.
+\end{quote}
+
+\noindent the paragraph continues, so there should not be a first-line
+indent.
+
+The quote below ends a paragraph:
+
+\begin{quote}
+Lorem ipsum dolor sit amet, consectetur adipiscing elit.
+\end{quote}
+
+\indent This paragraph, then, is genuinely a new paragraph and starts
+with a first-line indent.
+
+\hypertarget{further-tests}{%
+\section{Further tests}\label{further-tests}}
+
+After a heading (in English typographic style) the paragraph does not
+have a first-line indent.
+
+In the couple couple of paragraphs that follow the quotes below, we have
+manually specified \texttt{\textbackslash{}noindent} and
+\texttt{\textbackslash{}indent} respectively. This is to check that the
+filter doesn't add its own commands to those.
+
+\begin{quote}
+Lorem ipsum dolor sit amet, consectetur adipiscing elit.
+\end{quote}
+
+\noindent Manually specified no first line indent.
+
+\indent Manually specified first line ident.
+
+We can also check that indent is removed after lists:
+
+\begin{itemize}
+\tightlist
+\item
+  A bullet
+\item
+  list
+\end{itemize}
+
+\noindent And after code blocks:
+
+\begin{Shaded}
+\begin{Highlighting}[]
+\KeywordTok{local}\NormalTok{ variable }\OperatorTok{=} \StringTok{"value"}
+\end{Highlighting}
+\end{Shaded}
+
+\noindent Or horizontal rules.
+
+\begin{center}\rule{0.5\linewidth}{0.5pt}\end{center}
+
+\noindent In this document we added a few custom filter options. The
+size of first-line indents is 2em instead of the standard 1em. We also
+added an option to remove indent after tables:
+
+\begin{longtable}[]{@{}rlcl@{}}
+\caption{Demonstration of simple table syntax.}\tabularnewline
+\toprule
+Right & Left & Center & Default \\
+\midrule
+\endfirsthead
+\toprule
+Right & Left & Center & Default \\
+\midrule
+\endhead
+12 & 12 & 12 & 12 \\
+123 & 123 & 123 & 123 \\
+1 & 1 & 1 & 1 \\
+\bottomrule
+\end{longtable}
+
+\noindent So this paragraph's first line is not indented. And we
+included custom options \emph{not} to remove ident after ordered lists
+and definition lists:
+
+\begin{description}
+\tightlist
+\item[Definition]
+This is a definition block.
+\end{description}

+This paragraph is indented.

+\begin{enumerate}
+\def\labelenumi{\arabic{enumi}.}
+\tightlist
+\item
+  An ordered
+\item
+  list
+\end{enumerate}
+
+This paragraph is indented.

+First paragraph. In English-style typography, the first paragraph shouldn't have a first-line indent, nor the paragraphs below headers.
+
+This paragraph should start with a first-line indent. But after this quote:
+
+> Lorem ipsum dolor sit amet, consectetur adipiscing elit.
+
+the paragraph continues, so there should not be a first-line indent.
+
+The quote below ends a paragraph:
+
+> Lorem ipsum dolor sit amet, consectetur adipiscing elit.

+\indent This paragraph, then, is genuinely a new paragraph and starts with
+a first-line indent.
+
+# Further tests
+
+After a heading (in English typographic style) the paragraph does not have a first-line indent.
+
+In the couple couple of paragraphs that follow the quotes below, we have manually specified `\noindent` and `\indent` respectively. This is to check that the filter doesn't add its own commands to those.
+

+
+\noindent Manually specified no first line indent.
+
+\indent Manually specified first line ident.

+
+And after code blocks:
+
+```lua
+local variable = "value"
+```
+
+Or horizontal rules.

+
+In this document we added a few custom filter options. The size of first-line
+indents is 2em instead of the standard 1em. We also added an option to remove indent after tables:
