As a follow-up to an earlier question about how to customize biblatex-chicago to have it format a journal's volume and issue number as "volume.number", I would now like to know if there is a simple way to make to fix the output produced by @gusbrs's answer to that question.
MWE:
\documentclass{article}
\usepackage[notes]{biblatex-chicago}
\begin{filecontents*}{\jobname.bib}
@article{browning1964byz.scholarship,
Author = {Browning, Robert},
Journal = {Past \& Present},
Number = {28},
Pages = {3--20},
Title = {Byzantine Scholarship},
Year = {1964}}
\end{filecontents*}
\addbibresource{\jobname.bib}
% solution from @gusbrs
\DeclareFieldFormat{journum}{#1}
\usepackage{xpatch}
\xpatchbibmacro{cjournal+ser+vol+num}{% search
\printfield[jourvol]{volume}%
\setunit{\addcomma\addspace}}{% replace
\printfield[jourvol]{volume}%
\setunit{\adddot}}
{}{}% <success> and <failure>
\pagestyle{empty}
\begin{document}
\cite{browning1964byz.scholarship}
\end{document}
Current output is:
Robert Browning, "Byzantine Scholarship," Past & Present.28 (1964): 3–20.
I would like it to become:
Robert Browning, "Byzantine Scholarship," Past & Present 28 (1964): 3–20.
(space rather than period between journal title and issue number).
