                             BASH PATCH REPORT
                             =================

Bash-Release: 3.2
Patch-ID: bash32-049

Bug-Reported-by:        Len Lattanzi <address@hidden>
Bug-Reference-ID:       <address@hidden>
Bug-Reference-URL:      

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.

Patch:
