<div class="node-form"> not produced in form when cfreating a node

When editing an existing node of any type, a <div class="node-form"> is included before the edit form.

When inserting a new node, the same form naturally appears BUT the <div class="node-form"> is NOT included.

This poses a problem of certain node.css styles not taking effect when inserting a new node.

For example, the width of 1-line text fields is shorter (browser default) when inserting a node than when editing a node because the following statement in node.css does not take effect in insert:

.node-form .form-text {
   display: block;
   width: 95%;
}
