Description of problem:  The prompt sequences \[ and \] are broken in
the latest development bash.  (I upgraded from bash-3.0-18 (latest FC3
errata) to bash-3.0-22 (development tree) to pick up the fix for bug
139306, and saw this regression.)

These sequences are documented in man bash as:

  \[     begin  a sequence of non-printing characters, which could
         be used to embed a terminal  control  sequence  into  the
         prompt
  \]     end a sequence of non-printing characters


Version-Release number of selected component (if applicable):
bash-3.0-22
(bug did not exist in bash-3.0-18)

How reproducible: always

Steps to Reproduce:
1. run bash inside something xterm-ish
2. export PS1="\u@\[\033[32m\]\h\[\033[0m\] `uname -s` (\$?) \w \\\$ "
(yep, that's really my prompt string!)
3. type a bunch of characters at the prompt, until the line wraps
  
Actual results:
the characters start wrapping 9 characters before the right edge of
the terminal window

Expected results:
characters wrap at the edge of the terminal window, just as they do when
PS1="\u@\h `uname -s` (\$?) \w \\\$ "
