Wrapping isn't something that PmWiki does, it's a function of the
browser, the skin, and the semantics of HTML's "box model" for controlling

In the absence of any specific width information, text lines that 
wrap do so up to the width of the container of those lines, and the 
width of the container is generally at least as wide as the widest
item within it.

So, if there's a really long preformatted text line, the container
ends up being as wide as the line, and all other wrapping lines
do so at the width of the container.  (If the <pre> line is the widest
element, then none of the other lines wrap simply because they never
hit the right margin.)

The only way I know to avoid this is to explicitly force <pre>
sections to wrap at a certain point (as you've done), or to
do various CSS tricks that don't work in all browsers.

If anyone has any other suggestions, I'm open for them.  :-)
