Panvimwiki reference_citation creates reference links [#ref-name]: URL instead of [#name]: URL in markdown.
  pandoc --citeproc --metadata='link-citations:true' \
    --from=markdown+wikilinks_title_after_pipe-task_lists \
    --standalone --wrap=auto \
    --to=markdown-citations \
    expand_citeproc.md | reference_citation  > out/expand_citeproc-markdown.md
  Pandoc produces the following markdown references:
  ::::: {#refs .references .csl-bib-body .hanging-indent entry-spacing="0"}
  ::: {#ref-bloggs-jones .csl-entry}
  Bloggs, A. J., and X. Y. Jones. 1959. "Title Title Title Title Title

  The reference_citation filter converts the pandoc output to:

  Title Title Title Title Title." *Journal Journal Journal*.
  [#ref-chomsky-73]: Chomsky, N. 1973. "Conditions on Transformations." In *A Festschrift for
