Moin does not parse URL's with angle brackets properly

[noloader]

Debian uses Moin for its wiki at https://wiki.debian.org/. Moin does not parse a URL delimited with angle brackets properly, and it results in broken links when a page is rendered.

When Moin generates the http page and provides a link to the debian-user mailing list message, the linked url includes the closing angle bracket ('>'). The angle brackets are not part of the url.

Double quotes, angle brackets and whitespace are the commonly accepted ways to delimit a URL. From RFC 3986, Appendix C, Delimiting a URI in Context, https://datatracker.ietf.org/doc/html/rfc3986#appendix-C:

In practice, URIs are delimited in a variety of ways, but usually
within double-quotes "http://example.com/", angle brackets
<http://example.com/>, or just by using whitespace:

   http://example.com/

These wrappers do not form part of the URI.
...
Using <> angle brackets around each URI is especially recommended as
a delimiting style for a reference that contains embedded whitespace.

For example, this block of test was added to the "cdrecord" page at <https://wiki.debian.org/cdrecord> on the wiki:

<SNIP>
If you are having trouble writing CDs using cdrecord, then see Thomas Schmitt's analysis at "trixie: cdrecord can no longer write to CD" (November 2025), <https://lists.debian.org/debian-user/2025/11/msg00308.html>.
</SNIP>

Notice Moin rendered the page with the following link, which results in a 404 Not Found due to including the closing angle bracket:
