Author profile widget links

We can use parameters from the_author_meta, however including something like this does not work: <a href="mailto:{user_email}">{user_email}</a>

On the other hand, if I only specify {user_email} the email address is displayed, but without its link. Not very useful.

Also…
This works:
<dd><a href="{user_url}">View Author's page</a></dd>

This does not work and would be preferred:
<dd><a href="{user_url}">{display_name}</a></dd>
