problem with wrapfig as one paragraph text is not correctly terminated

[u-fischer]

lipsum add a (imho unnecessary) group around the whole processing. And if only one paragraph is typeset it doesn't add a par before ending the group. That is a problem for wrapfig as it looses its \everypar settings:

\documentclass{article}
\usepackage{wrapfig}
\usepackage{lipsum}
\textwidth=5cm
\begin{document}

\begin{wrapfigure}{o}{2cm}
XXX\\XXX\\XXX
\end{wrapfigure}
\lipsum[43]

\bigskip

%wrong:
\begin{wrapfigure}{o}{2cm}
XXX\\XXX\\XXX
\end{wrapfigure}
{abc abc abc abc abc abc abc abc abc abc
 abc abc abc abc abc abc abc abc abc abc}

\bigskip
% better (but not group at all would be best):
\begin{wrapfigure}{o}{2cm}
XXX\\XXX\\XXX
\end{wrapfigure}
{abc abc abc abc abc abc abc abc abc abc
 abc abc abc abc abc abc abc abc abc abc
 \par}

\end{document}
