Regression in shells/bash (bash-4.3.0) when selecting command after reverse incremental search, the command line isn't repainted as done in previous versions

[Trond Endrestøl]

Hi,

Has anyone else noticed this regression in shells/bash 
(bash-4.3.0(1))?

Here's one example:

1. Type this command and hit the enter key:

bash --version

2. Hit C-r and type the letter v.

3. The command line changes to:

(reverse-i-search)`v': bash --version

4. The cursor/point is placed on the letter v in --version.

5. Hit the enter key to execute the command.

6. The command line changes into:

trond at enterprise:~>bash --

7. The output is as expected though:

GNU bash, version 4.3.0(1)-release (amd64-portbld-freebsd9.2)

8. Hit C-r again and type the letter v.

9. The command line changes again into:

(reverse-i-search)`v': bash --version

10. The cursor/point is still on the letter v.

11. This time hit C-e to place the cursor/point at the end of the 
command line.

12. The command line changes into:

trond at enterprise:~>bash --version

13. This time the command line appears in its entirety.

14. Hit the enter key to execute the command.

15. The output is unchanged:

This "regression" can be due to the contents in my .inputrc file or 
some of the other files read by bash, but I'm inclined to believe the 
bug is related to bash's use of libreadline and/or libncurses.

For sake of argument, here's my .inputrc (the comments are in 
Norwegian, sorry):
