bug#17369: 24.4.50; several lines form a block of lines after inserting paren

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

To reproduce start emacs -Q and:
1. Type the following contents
a
{
b
}
2. Confirm that while standing on "b" and pressing END you just land 
after the "b".
3. After "a" insert "{" and delete it
4. Try to END from "b", and notice you land at the end of the file.

Expected behaviour: In step 4 we should land after "b".

May be connected with "newline chache" thread [1].
