bug#16227: 24.3.50; info documentation: Command Index not clickable (no links)

[Jarek Czekalski <jarekczek@poczta.onet.pl>]

Other indexes appear with links in the left column.
The items are clickable and the related info entry opens.
But with Command Index the case is different.
I have no links in this index.
Expected behaviour: Command Index should be clickable.

To be specific. This page displays correctly:
(info "(emacs)Variable Index")
and this one does not:
(info "(emacs)Command Index")
