The problem with a long node is that, when something links to that node,
it is not easy to find what the pertinent text in that node.
For example, if the text about re-search-forward is in a large node,
the link from the index will point to the start of the node.
It will be a hassle to find that text in the node.

Therefore we subdivide nodes when they are inconveniently long.

Having a parent node with a number of subnodes is the way we
handle this.  The Lisp Manual already seems to be set up that way.
Do you think a change is needed there?

It looks like the Emacs Manual could use a small reorganization to a similar
structure.  Would you like to propose a patch?
