Bash-Release: 3.2
Patch-ID: bash32-050

Bug-Reported-by:	Jan Hnatek <Jan.Hnatek@Sun.COM>
Bug-Reference-ID:	<4A44991F.8010005@sun.com>
Bug-Reference-URL:	http://lists.gnu.org/archive/html/bug-bash/2009-06/msg00084.html

Bug-Description:

On systems where mbrtowc() returns -2 when passed a length argument with
value 0, when using a multibyte locale, Readline's emacs-mode forward-char
at the end of a line will leave the point beyond the end of the line.
