less table robust against type renumbering.

* lib.c (less_tab_init): The type_prec table initialization
will become incorrect if new type enums are added other than
at the end. Let's switch to assignments. Anything not
mentioned is zero.

* lib.h: Add more advice to comment about extending type_t:
consider all places where MAX_TYPE is used.
