 If you change your email address to one including an ampersand then we
 mangle the address with html entities.

 For example:
  * This - peter&paul at sitting.in.a.tree.com
  * Becomes - peter&paul at sitting.in.a.tree.com

 This is due to the call to {{{wp_filter_kses}}} on {{{pre_user_email'}}}
 in {{{default-filters.php}}}.

 The was added in [5906] for #4546.

 I'm not sure if we need kses filtering for emails - if we do which should
 probably revert this conversion of the & => & afterwards.
