There's no easy way for us to complete aliases for root; we don't even
know what shell sudo will run its command under.

However, we could add a layer of indirection so people can fill this in
their own configs:

[[[
_arguments ... '(-)1:command:_sudo_command'

_sudo_command() {
  if -i or -s passed:
    _sudo_aliases
  else
    _command_names
  fi
}

_sudo_aliases() {
  _command_names -e
}
]]]

... and document that _sudo_aliases is intended to be
overwritten/redefined by a user's .zshrc file.
