Previously, using `--citeproc` could cause punctuation to move in
quotes even when there aer no citations. This has been changed;
now, punctuation moving is limited to citations.
In addition, we only move footnotes around punctuation if the
style is a note style, even if `notes-after-punctuation` is `true`.
This affected author-in-text citations in footnotes.
It didn't cause problems for the printed output, but for
filters that expected the citation id and other information.
