Bug#922418: pandoc: Please reference texlive-latex-base package in the "install pdflatex" error message

[Chris Lamb <lamby@debian.org>]

Source: pandoc
Version: 2.2.1-3
Severity: minor
Tags: patch

Hi,

  % pandoc -o output.pdf input.md
  pdflatex not found. Please select a different --pdf-engine or install pdflatex

I think this could be improved user-interface wise as pdflatex is
in the "texlive-latex-base" package (and not a hypothetical "pdflatex"
package).

A patch is attached that turns this into:

  % pandoc -o output.pdf input.md
  pdflatex not found. Please select a different --pdf-engine or install pdflatex from the texlive-latex-base package


Best wishes,
