Since it was proposed in

http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00454.html

instead of implementing `Info-index-occur' I arrived to a different
command name: `info-apropos-current-file'.  I don't know if this is
a better name, but by its functionality this command is very similar
to `info-apropos' that works only on the current Info file.
