This way users connect to "you@gerrit.com" rather than the much longer (and uglier) "you@gmail.com@gerrit.com". We still generate the user from the email, preventing end-users from selecting their own SSH name. We could in the future change this if there is sufficient demand. Because we validate both the username and the SSH public key we can only run into name duplication problems if multiple accounts have the same local name in their preferred email address and use the same SSH public key, which should only be possible if they are both using "root@..." as their email and both keys were created on Debian with the infamous broken ssh-keygen implementation.
