biblatex-verbose: Comma after editor instead of period

The period after “Editor” should be a comma. I tracked down the byeditor+others bibmacro, but couldn’t figure out what I needed to change. A \DeclareFieldFormat, which has helped with punctuation in other cases, didn’t help either.

\documentclass{article}

\usepackage[style=verbose]{biblatex}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@incollection{foo,
author = {Author},
title = {Title},
booktitle = {Booktitle},
editor = {Editor},
location = {Location},
year = {2013},
}
\end{filecontents}

\begin{document}
\nocite{foo}
\printbibliography
\end{document}


I don't know if the following is the best method, but substituting \newunit with \addcomma in the definition of byeditor+others works.

\renewbibmacro*{byeditor+others}{%
\ifnameundef{editor}
{}
\printnames[byeditor]{editor}%
\clearname{editor}%
\usebibmacro{byeditorx}%
\usebibmacro{bytranslator+others}}

year = {2013},

\renewbibmacro*{byeditor+others}{%

\printnames[byeditor]{editor}%
\clearname{editor}%
