Fields with errors look ugly in stacked forms

Created by: wildchild

Quick fix:

form.form-stacked div.error {
  margin-top: 0;
}

But I believe it could look better:

form.form-stacked div.error {
  padding-top: 10px;
  padding-bottom: 10px;
  padding-left: 10px;
  margin-top: 0;
  margin-left: -10px;
}

Any ideas?
