+ elements</p>combined</li>", each with different effects. It would
+ be best to stick with strict body elements in list items, but they
+ affect vertical spacing in browsers (although they really
+ shouldn't).
+
+ Here is an outline of the optimization:
+
+ - Check for and omit <p> tags in "simple" lists: list items
+ contain either a single paragraph, a nested simple list, or a
+ paragraph followed by a nested simple list. This means that
+ this list can be compact:
+
+ - Item 1.
+ - Item 2.
+
+ But this list cannot be compact:
+
+ - Item 1.
+
+ This second paragraph forces space between list items.
+
+ - Item 2.
+
+ - In non-list contexts, omit <p> tags on a paragraph if that
+ paragraph is the only child of its parent (footnotes & citations
+ are allowed a label first).
+
+ - Regardless of the above, in definitions, table cells, field bodies,
+ option descriptions, and list items, mark the first child with
+ 'class="first"' and the last child with 'class="last"'. The stylesheet
+ sets the margins (top & bottom respecively) to 0 for these elements.
+
+ The ``no_compact_lists`` setting (``--no-compact-lists`` command-line

+ * textwidth - the width of text on the page

+ *Bug* inside a minipage a (e.g. Sidebar) the linewidth is
