The following, when rendered on the website,

# minimalReprex 0.0.0.9000

* @maelle fixed this bug in PR XYZ.

* Thanks, @maelle, for discovering this bug.

* Added a `NEWS.md` file to track changes to the package.

looks like this:

What a great username example :wink: Thanks for the reprex.

Regex https://github.com/r-lib/pkgdown/blob/25a1ab2d04c2b8251214b5189fa6735896468cd7/R/repo.R#L41 Tests https://github.com/r-lib/pkgdown/blob/25a1ab2d04c2b8251214b5189fa6735896468cd7/tests/testthat/test-repo.R?q=repo_auto_link#L12

Maybe the regex should be tweaked, or maybe this behavior is intended, I am afraid I do not know which. :sweat_smile:

I can't reproduce:

text <- "# minimalReprex 0.0.0.9000

* @maelle fixed this bug in PR XYZ.

* Thanks, @maelle, for discovering this bug.

* Added a `NEWS.md` file to track changes to the package."

pkg <- list(
  repo = list(
    url = list(
      user = "http://example.com/users/"
    )
  )
)
cat(pkgdown:::repo_auto_link(pkg, text))
#> # minimalReprex 0.0.0.9000

But I do see it with a fuller reprex:

pkg <- local_pkgdown_site(meta = "
  repo:
    url:
      user: https://example.com
    ")
write_lines(path = file.path(pkg$src_path, "NEWS.md"), 
"# testpackage 0.0.0.9000

* @maelle fixed this bug in PR XYZ.

* Thanks, @maelle, for discovering this bug.

* Added a `NEWS.md` file to track changes to the package."
)
cat(build_news(pkg)$html)

Oh, because the text being processed is HTML:

<div id="testpackage-0009000" class="section level2">
<h2 class="page-header" data-toc-text="0.0.0.9000">testpackage 0.0.0.9000</h2>
<ul><li><p>@maelle fixed this bug in PR XYZ.</p></li>
<li><p>Thanks, @maelle, for discovering this bug.</p></li>
<li><p>Added a <code>NEWS.md</code> file to track changes to the package.</p></li>
</ul></div>

Minimal reprex:

pkg <- list(
  repo = list(
    url = list(
      user = "http://example.com/users/"
    )
  )
)
cat(pkgdown:::repo_auto_link(pkg, "<p>@maelle</p>"))
#> <p>@maelle</p>

Reopening since my fix didn't handle the case of pre-existing links (#2122) and I had to revert it.
