If I process this markdown file ('mwe-latex.md'):
---
title: "Minimal Working Example"
header-includes:
- \let\oldsection\section
- \renewcommand{\section}[1]{\clearpage\oldsection{#1}}
---
Text.
with the pandoc command:
pandoc -t latex --latex-engine=xelatex --output=mwe-latex.pdf mwe-latex.md
I get the the error:
! LaTeX Error: Missing \begin{document}.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.49 \let\oldsection\textbackslash{}s
pandoc: Error producing PDF
On generating latex output with the command:
pandoc -t latex --latex-engine=xelatex --standalone --output=mwe-latex.tex
mwe-latex.md
and examining line 49 of the output file it becomes apparent that this line
from the header inclusion:
\let\oldsection\section
has been munged by pandoc to:
\let\oldsection\textbackslash{}section
and this is causing the processing problem. (Note: changing latex engines
makes no difference.)
Once line 49 is edited to resemble the original command from the header
inclusion the error disappears.
How can I prevent this latex command in the header inclusion from being
munged by pandoc?

See https://github.com/jgm/pandoc/issues/2956
Alternatively, in the dev version of pandoc you can tell
it you've got raw latex, not Markdown:
header-includes:
- `\let\oldsection\section`{=latex}
Final remark: I don't understand why it's not parsing
the `\section` as raw tex. I'll need to look into this;
it may be a bug in the LaTeX reader.

Can't install dev pandoc because the ghc archive downloaded as part of the
process is corrupt.
Once downloaded, the command:
tar xf ghc-8.0.2.tar.xz
results in:
xz: (stdin): Compressed data is corrupt
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now

Not sure of the relevance of issue 2956, which is about pandoc not
recognising options in parentheses. There are no parentheses in the
problematic header inclusion.

You could try installing one of the nightlies from
https://github.com/pandoc-extras/pandoc-nightly instead.

Pandoc will mangle sundry other things as well including,
sometimes, curlies which it things are not argument delimiters.
I've tried in vain to see a pattern in that. The workaround John
mentioned (the dummy command) works in all these cases (or at
least all cases I've come up against as yet!)

Using a nightly worked. Here is a better minimal working example that shows
the effect of the redefined command:
---
title: "Minimal Working Example"
header-includes:
- \let\oldsection\section
- \renewcommand{\section}[1]{\clearpage\oldsection{#1}}
---
# Heading 1 #
Text 1.
# Heading 2 #
Text 2.
The command
pandoc -t latex --latex-engine=xelatex --output=mwe2.pdf mwe2.md
results in a pdf file with each heading on a new page. Producing latex
output shows the header inclusions inserted without alteration - without
needing the "backtick" notation John mentioned.
Guess I'm using a pandoc nightly until this behaviour migrates into
debian/testing :-)
Thanks John, Roland and BP for chipping in to help me.
P.S. It's been ages since I used Google Groups. If there is any way to mark
this post or thread "solved" please let me know and I will.
