I sent this reply tonight:
http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-05/msg00476.html
The summary is that the case you are wondering about didn't have the bug
at all.
I tried to reproduce the bug in all three cases with emacs-24 revision
107933. The first case "emacs -Q" had the bug; "emacs -nw" had the bug;
"emacs -fn fixed" didn't have the bug.
Then I updated to revision 107934 (your patch). That fixed the "emacs
-nw" case. My tweak fixed the "emacs -Q" case.
