BASH PATCH REPORT
=================
Bash-Release: 3.2
Patch-ID: bash32-031
Bug-Reported-by: Miroslav Lichvar <mlichvar@redhat.com>
Bug-Reference-ID: Fri, 02 Nov 2007 14:07:45 +0100
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-readline/2007-11/msg00000.html
Bug-Description:
In certain cases when outputting characters at the end of the line,
e.g., when displaying the prompt string, readline positions the cursor
incorrectly if the prompt string contains invisible characters and the
text being drawn begins before the last invisible character in the line.
Patch:
