Link detection fails when URL is prefixed with `@` character

[thedoom13]

Hi! I noticed that when a URL is prefixed with certain characters, the link is still detected correctly.
However, when prefixed with the @ character, the URL is not detected at all.

Examples

Works as expected:

• >https://example.org → detects https://example.org
• !https://example.org → detects https://example.org
• #https://example.org → detects https://example.org

Does not work:

• @https://example.org → no link detected

Is this the expected behavior, or should this be handled as a special case?

Thanks!

Not sure, do you have a use case for supporting this? If it's simple to fix and doesn't break anything I'd be happy to accept a PR.
