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

Readline-Release: 8.2
Patch-ID: readline82-013

Bug-Reported-by:        Grisha Levit <grishalevit@gmail.com>
Bug-Reference-ID:       <CAMu=Brrv5qKY6LPfw8PxqNXNO8rNsZo0Fb=BcFb-uHObWPqnrw@mail.gmail.
Bug-Reference-URL:      https://lists.gnu.org/archive/html/bug-bash/2023-04/msg00082.html

Bug-Description:

When readline is accumulating bytes until it reads a complete multibyte
character, reading a byte that makes the multibyte character invalid can
result in discarding the bytes in the partial character.

Patch (apply with `patch -p0'):
