I think I prefer the original behavior (but actually, I use a private
version of `word-search-regexp' that behaves entirely differently, so my
opinion doesn't matter).  But apart from that, the patch doesn't work as
expected (even with the other patch that adds indication also
installed):

- in emacs -Q, hit C-h i to go to the info top dir

- I want to word search for "directory".  point is at point-min.

- I hit d.  Isearch jumps to the "d" in "Type "d" in Info to..."

- I type the remaining letters: "irectory".  The isearch prompt says
  "Failed" apparently because I'm now past all matches and isearch
  didn't reconsider the text before the first match "d".
