Bash-Release: 3.0
Patch-ID: bash30-009

Bug-Reported-by: Tim Waugh <twaugh@redhat.com>
Bug-Reference-ID: <20040810083805.GT2177@redhat.com>
Bug-Reference-URL: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=129526b

Bug-Description:

-->
Steps to Reproduce:
1. Launch a bash shell
2. Set editing mode to 'vi' with 'set -o vi'
3. Type any command, but don't hit return
4. Enter vi-command mode by hitting the escape key
5. Go to the end of line with the '$' command
6. Type 'r' to change the last character
7. Type any character (other than what the character already is)

The last two characters are inexplicably swapped
after the last character is changed.
