w3m-next-form is a misnomer

[jidanni@xxxxxxxxxxx]

Regarding the docstrings and Info for "[":
   w3m-next-form is an interactive compiled Lisp function in `w3m.el'.
   It is bound to ].
   Move the point to the next form.

   `]'
	Move the point to the next form.  More strictly speaking, move the
	point forwards to the nearest form (`w3m-next-form').

More strictly speaking, the next entry area or whatever, of what
often is in fact the _same_ <form>, not next <form>.

So the command is a misnomer.

At least in the documents mention that it is not necessarily the next
form.

Same for "]".
