GP defaults, help sections (1 to 11) as well as some keywords (readline,
bnf, ell, all operators...) are recognized and treated in a special way to
make sure they match a section heading. For instance

The search algorithm is rather crude and the data searched rather
unstructured. Hence, searching outside of Chapter 3 may not yield useful
