- open a new buffer in fundamental mode, no auto-fill-mode
- insert a long line that will be wrapped for display into two or
more
lines.
- insert the following form into the buffer, after the long line
(add-text-properties (point-min) (point) '(line-prefix ""))
- evaluate this form
Expected result: No change in display
Actual result: The formerly wrapped line is no longer wrapped but
displayed as if truncate-lines had been set (it is not set)
Isn't this the feature you were asking for? ;-)
