% I may as well include my robust expandable definions, which can be
% used in \edef or \write where the \def would not be executed:
%
% \if\blank --- checks if parameter is blank (Spaces count as blank)
% \if\given --- checks if parameter is not blank: like \if\blank{#1}\else
% \if\nil --- checks if parameter is null (spaces are NOT null)
% use \if\given{ } ... \else ... \fi etc.
