Simply turning this on has an undesirable consequence that node names
are now hidden in the index node, but it is very useful to see them!
This is because index entries are not like normal links where nodes name
are not very essential.  I propose the following patch that doesn't hide
node names of the index entries while keeping index entries displayed
as links (blue and underlined).
