% Signatures, possibly multi-line
%
% For legacy reasons Sphinx uses LaTeX \list and \item's for signatures
% This is delicate:
% - the actual item label is not typeset immediately by \item but later as part
% of the \everypar which will be triggered by either next paragraph or a manual
% \leavevmode, or if nothing in-between by the next \item,
% - \begingroup <set-up>\item[foo] <setup>\endgroup leads to errors,
% - vertical space depends on \parskip and \itemsep values in somewhat
% subtle manners.
%
% Since the 2022/01/13 version things are simpler as \parskip is simply set
% to zero during execution of \pysigline/\pysiglinewithargsret
