(`lit2texi' only.) Alternate style of node linking -- puts in more defaults for "next" and "previous" nodes. If a node doesn't have a "next" ["previous"] at its level (e.g., it's the last section in a chapter), then its "next" ["previous"] node will be the physically-next [-previous] one, regardless of sectioning level. (The default is for such nodes to have no next [previous] node.)

[I like the -L node-linking scheme but `makeinfo' issues warnings about it. APRIL91: newer version of some Info readers achieve the same effect using additional moving-around-the-tree commands.]
