                           READLINE PATCH REPORT
                           =====================

Readline-Release: 5.2
Patch-ID: readline52-003

Bug-Reported-by: Peter Volkov <address@hidden>
Bug-Reference-ID: <address@hidden>
Bug-Reference-URL: 
http://lists.gnu.org/archive/html/bug-bash/2007-02/msg00054.html

Bug-Description:

When moving the cursor, bash sometimes misplaces the cursor when the prompt
contains two or more multibyte characters.  The particular circumstance that
uncovered the problem was having the (multibyte) current directory name in
the prompt string.

Patch:
