BASH PATCH REPORT
=================
Bash-Release: 4.0
Patch-ID: bash40-023
Bug-Reported-by: Andreas Schwab <schwab@linux-m68k.org>
Bug-Reference-ID: <m21vrhhx08.fsf@igel.home>

Bug-Description:
If the prompt length exactly matches the screen width, and the prompt ends
with invisible characters, readline positions the cursor incorrectly.
