Bash: wrapping long command line [SOLVED]

Question

I'm trying to configure my bash to wrap long command lines.  I am looking for a behaviour similar to tcsh where, at the border of the window,  the command is continued on the next line.  In bash, the command continues at the begining of the same lines wich is messy.  I tried using
set horizontal-scroll-mode on
in my ~/.inputrc but the continuation doesn't start at the windows border. I can post screenshots if that would help.
Thanks.

Answer 1

putting the line in .bashrc have no effect.
Here is my .bashrc
export EDITOR=emacs
export PAGER=less
export LESS="-f -r"
export BROWSER=firefox
PS1='[33[01;34m]#[33[00m] 33[01;31m]u@H[33[00m]33[01;39m] w $33[00m] '
# create an xauth key for root user
umask 377
/usr/X11R6/bin/xauth extract /tmp/user.xauth $DISPLAY
umask 022
#set horizontal-scroll-mode on
source ~/.aliases
my .bash_profile
. $HOME/.bashrc
my .inputrc
"e[A": history-search-backward
"e[B": history-search-forward
set show-all-if-ambiguous on
set page-completions off
set completion-query-items 10000
set horizontal-scroll-mode on
The screenshots:
With tsch (what I'm looking for)
With set horizontal-scroll-mode off:
If I continue to press the 'a' key, it overwrite the whole line and wraps at the window border.
With set horizontal-scroll-mode on:
It wraps 2 inches before reaching the window border.
