E-mail addresses are incorrectly interpreted as bracketed citations

[Witiko]

Writing [[email protected]](mailto:[email protected]) with citations option enabled is interpreted as a citation:

$ markdown-cli citations=true <<< '[[email protected]](mailto:[email protected])'

\markdownRendererDocumentBegin
\markdownRendererCite{1}+{translation}{}{castb.org}(mailto:[email protected])\markdownRendererDocumentEnd

However, this should only happen when there is whitespace before the @:

$ pandoc -f markdown+citations <<< '[[email protected]](mailto:[email protected])'

<p><a href="mailto:[email protected]">[email protected]</a></p>

$ pandoc -f markdown+citations <<< '[translation @castb.org](mailto:[email protected])'

<p><span class="citation" data-cites="castb.org">[translation @castb.org]</span>(mailto:[email protected])</p>

Pull request #426 should fix the issue:

$ docker run --rm -i ghcr.io/witiko/markdown:3.4.2-31-g02122159-TL2022-historic-no_docs markdown-cli citations=true <<< '[[email protected]](mailto:[email protected])'

\markdownRendererDocumentBegin
\markdownRendererLink{[email protected]}{mailto:[email protected]}{mailto:[email protected]}{}\markdownRendererDocumentEnd

$ docker run --rm -i ghcr.io/witiko/markdown:3.4.2-31-g02122159-TL2022-historic-no_docs markdown-cli citations=true <<< '<[email protected]>'

\markdownRendererDocumentBegin
\markdownRendererLink{[email protected]}{mailto:[email protected]}{mailto:[email protected]}{}\markdownRendererDocumentEnd
