Multi-paragraph abstract using memoir chapterprecis

Question

Having taken note of a way to have author's names and abstracts assigned to each chapter in a memoir class document (see add authors and abstract below memoir chapter title), I've run into a bit of a snag.

I wanted to add a bit of space in the TOC, which works fine. However, if I try to have a multi-paragraph abstract, the indentation works fine in the TOC, but not in the actual chapter; somehow, the instruction to indent seems to get swallowed up.

How can I fix this? MWE and relevant output follow:

\documentclass{memoir}
\newcommand\authorabstract[1]{%
    \chapterprecishere{\mbox{}\[\baselineskip]#1}%
    \chapterprecistoc{\[.5\baselineskip]#1\[.5\baselineskip]}%
}
\begin{document}
\frontmatter
\tableofcontents
\mainmatter
\chapter{First chapter}
% this goes into the document and the ToC
\authorabstract{Author\newline\newline First paragraph.\newline\indent Second paragraph.}
Chapter text here.
\end{document}

Correct indentation in TOC:

Missing indentation in the chapter:

Answer 1

memoir uses the environment quote (no inner indentation) to put together \prechapterprecis.

You might add a \parindent to \authorabstract to indent the second paragraph.

\documentclass{memoir}
\newlength{\docparindent}
\setlength{\docparindent}{\parindent} % save document indent
\newcommand\authorabstract[1]{%
    \chapterprecishere{\mbox{}\[\baselineskip]\parindent\the\docparindent#1}% changed <<<<<<<<
    \chapterprecistoc{\[.5\baselineskip]#1\[.5\baselineskip]}%
}
\begin{document}
    \frontmatter
    \tableofcontents
\mainmatter
\chapter{First chapter}
% this goes into the document and the ToC
\authorabstract{Author\newline\newline First paragraph.\newline\indent Second paragraph.}

Chapter text here.
