Link with E-mail address in Markdown

[user@example.com](user@example.com) now (GitLab 11.7.3-ee on gitlab.com) returns <a href="https://gitlab.example.com/namespace/project/branch/user@example.com">user@example.com</a>.

We should get <a href="mailto:user@example.com">user@example.com</a> instead?

Compared with the simplest form user@example.com, which results in <a href="mailto:user@example.com">user@example.com</a>.
