[texhax] wrapfig and subsection headers?

Not exactly the help you might be looking for, but you might try picins
instead of wrapfig. I append a previous posting of mine, though, that
shows similar problems with figures and list environments (which wrapfig
doesn't do at all, and which is why I use picins). Perhaps it will
behave better with sectioning though. I've tried to chase the authors of
picins, but they are no longer reachable. 

My use of this kind of thing suggests it is an area where a real texpert
is needed to improve on Latex's handling of figures. On my wish list

* a modern equivalent to picins

* a version of multicol that can handle floats

I am using the picins package to flow text around a figure. It has the
advantage over others (wrapfig and floatflt) that it works within list
environments. However, the attached example shows that it does not
properly restore the list indentation if used in only one of the list
items. The one following the picins is ok, but the 2nd and subsequent
after that is incorrect. In two-column mode, even the 2nd item doesn't 
get indented properly.

I have a workaroud, which is to put a blank \parpic at the end of each
following item. That adds a bit of vertical space but is otherwise ok.
Another workaround would be welcome.

It would seem that the author of this package is not traceable, and the
code too dense for me to figure out what is going wrong. Has someone
else hit/solved this? It's an old (latex209?) package; version 3.0.




\newcommand{\longtext}{Here is some long long text. Here is some long
text. Here is some long text. Here is some long text. Here is some long
text. Here is some long text. Here is some long text. Here is some long
text. Here is some long text. Here is some long text.}



This demonstrates an apparent bug in picins in connection with a
list-making environment. The first example illustrates the bug.



\item{}  \longtext
\item{}  \longtext
\item{}  \longtext
\item{}  \longtext
\item{}  \longtext


Note the incorrect indentation in the 3rd item, which is apparently
related to something parpic does that doesn't affect the 2nd. The next
example has a parpic in each item, and works ok.



\item{} \parpic[rf]{\begin{picture}(10,10)\put(0,4){HELP}\end{picture}}

\setlength{\unitlength}{1mm}  % this seems to need to be re-set each

\item{} \parpic[rf]{\begin{picture}(10,10)\put(0,4){HELP}\end{picture}}


\item{} \parpic[rf]{\begin{picture}(10,10)\put(0,4){HELP}\end{picture}}


End of test.
