Hi Richard, You should be able to get rid of that indentation by arranging for the text after the listing end to begin with \noindent{} (in LaTeX). This should be as simple, in org, as:
... #+END_SRC \noindent{}Lorem ipsum... I am not sure there is a way to automate the \noindent: LaTeX indents the beginning of paragraphs, and in org there is no way to have a paragraph that contains a source listing. (In latex there is: don’t leave a blank line after the \end{minted}. But I don’t think org has a way to represent/output such a thing. If I’m wrong about that I hope Nicolas or someone else knowledgeable will chime in.) I suppose it would be possible to write a filter to post-process the LaTeX output, and delete single blank lines after an \end{foo}, and indicate desired paragraph breaks with double blank lines. -- Aaron Ecay
