Hello,
I think I've found one (strange) situation where Isearch highlighting
doesn't seem to work well.
Steps to reproduce:
0) Start emacs (emacs -Q).
1) Open Emacs Manual (C-h r)
2) Go to node "(emacs)Error in Isearch" (g Error <TAB> <RET>)
3) Search for the word "foott" (C-s foott)
4) Remove the las "t" (<DEL>)
** Expected result: The last 3 occurrences of the word "foot" are
highlighted again with the `lazy-highlight' face.
** Actual result: Those 3 words don't get highlighted at all.
I've also tried to copy that section of the manual into a brand new
buffer, but there I can't reproduce the problem.

The difference between this recipe in a normal buffer and an Info buffer
is in the line
(when (not isearch-error)
in `isearch-lazy-highlight-new-loop'. A normal Isearch starts
a new lazy highlighting loop even if there are no matches,
so it has a chance to set `isearch-lazy-highlight-last-string'.
But an Isearch in Info has the text "Initial node" in `isearch-error',
so `isearch-lazy-highlight-new-loop' doesn't set the last search string
to `isearch-lazy-highlight-last-string'.
This bug is not specific to an Isearch in Info. You can get the same bug
for a regexp Isearch in a normal buffer as:
1) Search for the regexp "foot[" (C-M-s foot[)
2) Remove the last "[" (<DEL>)
There is no lazy highlighting too.
I think this patch is a general fix for all these bug cases:

Looks good to me, could you commit it to the emacs-23 branch? Thanks.

Ok, will do when bzr.savannah.gnu.org will be available. Currently bzr says:
Unable to connect to SSH host bzr.savannah.gnu.org; EOF during negotiation

Perhaps there is some misconfiguration on my side. `.bzr.log' says:
Unable to obtain credentials for {'protocol': 'ssh', 'server': 'bzr.savannah.gnu.org'}
from GNOME keyring: NoMatchError()
but from the command line I still can ssh to bzr.savannah.gnu.org
(that says "VCS commands are allowed"). I'll investigate now what is wrong.
