This gets rid of `divAttrToContainers`: an internal convenience function
which had become pretty inconvenient. Rather than converting classes and
indentations to string lists and back, we deal with the `pPr` attribute
directly.
Here, when hanging indents are greater than or equal to left indents, we
don't set it to block quote. Such indents are frequently used in
academic bibliographies. (Thanks to Caleb McDaniel.)
Previously, a fresh state was created for the purpose of updating. In
the future, when there is more than one field in the state, this
obviously won't work.
This is a ReaderT State stack, which keeps track of some environment info, such
as the options and the docx doc. The state will come in handy in the future,
for a couple of planned features (rewriting the section anchors as auto_idents,
and hopefully smart-quoting).
The normalizing tests revealed a problem with unformatted spaces, brought about
by `spanTrim`. This fixes by not trimming the spaces out of spans until they
are in their final form.
There were some problems with the old str normalization. This fixes those
problems. Also, since it drills down on its own, it only needs to be
mapped over the blocks, not walked over the tree.
`normalize` from Text.Pandoc.Shared is more general. In tests, though,
it more than doubles the run time. `strNormalize` does less, but it does
what we need. This comment is added for future maintainability.
Use a function `stripSpaces`, instead of recursion. Makes it a bit
easier to read and mantain, and simplify normalizing DefinitionList,
which was left out the first time.
