bug#1452: 23.0.60; Problem with nextstep, longlines-mode,

[Harald Hanche-Olsen]

The following happens on mac os x, nextstep build.
It does NOT happen on freebsd, x11 build.
(Those are the only two places I have tried.)

M-x set-variable RET longlines-show-hard-newlines RET t
C-x b asdf RET
M-x longlines-mode RET
Type some text in the buffer, followed by RET
Type some more text. Bug symptom #1: Nothing happens.
M-x longlines-mode RET. Bug symptom #2:
 The longlines-show-effect string is not cleaned out right, leaving
 the buffer contents looking as follows:

----
asdf
adsf----

I expect this bug is not at all specific to longlines-mode, but that
it is a text property related bug in the nextstep implementation.
