Description Jan Kratochvil 2007-10-30 14:29:11 UTC

Description of problem:
My standard PS1 positions cursor incorrectly in the prompt.
It may be a readline specific bug.

Version-Release number of selected component (if applicable):
bash-3.2-18.fc8.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. PS1='\[\017\]xyz'
2. LC_CTYPE=en_US.UTF-8
  
Actual results:
Prompt cursor position is at the character 'z'.

Expected results:
Prompt cursor position is right behind the character 'z'.

Additional info:
\017 should set the standard character map to fixup terminal after a possible:
$ cat GARBAGE
