#14441 — [PATCH] Re-display prompt if directory changed in a bind -x command

[Multipart message — attachments visible in raw view] — view raw

Using bind -x to call cd or source a script that changes the directory
will not update the prompt to show the new directory after the script
finished:

user@host:~$ bind -x '"\C-t": "echo test;cd /"'

# I press Ctrl-T
test
user@host:~$

Prompt still shows ~ as the pwd. Once I press Return or Ctrl-L the
prompt shows root as the pwd.

Updating the prompt is useful when using the mc-wrapper.sh script for
Midnight Commander that changes the bash pwd to the last mc directory
when mc exits. There is a similar wrapper for vim for example.

Attached patch decodes the prompt string again after running the
command passed to bind -x.

Regards,
Bogdan
