+ READLINE PATCH REPORT
+ =====================
+
+Readline-Release: 5.2
+Patch-ID: readline52-010
+
+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:
