BASH PATCH REPORT
=================
Bash-Release: 3.1
Patch-ID: bash31-014
Bug-Reported-by: Mike Stroyan <mike.stroyan@hp.com>
Bug-Reference-ID: <20060203191607.GC27614@localhost>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2006-02/msg00004.html
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.
