pius fails to recognize user IDs that have a raw e-mail address as being an e-mail address

[dkg]

Some OpenPGP certificates have a User ID that is a raw e-mail address, like [email protected]. This is not commonplace, but it does happen, and GnuPG supports it these days.

When pius tries to sign a User ID like that, it produces an error:

UID 2 ([email protected]): signed  WARNING: No email for [email protected], cannot send key.

instead, it should treat it the same way that it treats a User ID that contains <[email protected]>.

Please give me an example of a key to test on.
