Memoir: Remove indentation in abstract

Question

I would like to automatically remove the indentation at the beginning of an abstract in memoir. I have seen such solutions for other classes. If I insert \noindent manually like this:

\documentclass{memoir}

\usepackage{lipsum}

\begin{document}

    \begin{abstract}
        \noindent
        \lipsum[1]    
    \end{abstract}

\end{document}

Then the indentation is removed completely: I tried to modify \abstracttextfont, but a small indentation remains:

\documentclass{memoir}

\usepackage{lipsum}

\renewcommand{\abstracttextfont}{\normalfont\small\noindent}

\begin{document}

    \begin{abstract}
        \lipsum[1]    
    \end{abstract}

\end{document}

Answer 1

It is probably simplest to just use

\renewcommand{\abstracttextfont}{\normalfont\small\noindent\ignorespaces}
