|
Bug-Description:
|
||
|
|
|
||
|
|
The displayed search prompt is corrupted when using non-incremental
|
||
|
|
searches in vi and emacs mode if the prompt contains non-printing
|
||
|
|
characters or spans multiple lines. The prompt is expanded more than
|
||
|
|
once; the second time without the escape sequences that protect non-
|
||
|
|
printing characters from the length calculations.
