Notice this commit updates lists.docx. The old test file contained
references to "ListParagraph" style, which should never leak
outside of pandoc, so I'm not sure what that was supposed to test
for exactly.
It makes more sense not to interpret -- otherwise using the original
document as the reference-doc would produce two of everything: the
interpreted version and the uninterpreted style version.
Previously Emph, Strong, etc were outside the custom-style span. This
moves them inside in order to make it easier to write filters that act
on the formatting in these contents.
Tests and MANUAL example are changed to match.
The previous commit had a bug where custom-style spans would be read
with every recurrsion. This fixes that, and changes the example given
in the manual.
