%%% Testing: textblock in horizontal mode
%
% In textpos up to 1.9.1, a textblock in horizontal mode, with the
% [absolute] option, worked, in the sense of not failing, but produced
% ugly spacing, because in generating a `\par` it messed up
% inter-paragraph spacing.  This had the result that the text either
% side of the textblock appeared as separate paragraphs with no space
% between them.  The appearance in [relative] mode was OK, but with
% the `\par` visible.  This isn't a _bug_, since the documentation
% didn't say anything other than that a `\par` is inserted at this
% point, but it's not pretty.
