In a terminal window any smaller than fullscreen, if I type in a long command it starts overwriting the current line I'm on. If I type an additional line's worth, it finally moves to the next line. Does anyone know how to fix this?

This is what happens visually:

Edit: These are my prompt settings:

PS1='[e]0;u@h: wa]${debian_chroot:+($debian_chroot)}u@h:w033[1m`__git_ps1`033[0m$ '

TERM=xterm

.bashrc:

if [ "$color_prompt" = yes ]; then

    PS1='${debian_chroot:+($debian_chroot)}[033[01;32m]u@h[033[00m]:[033[01;34m]w[033[00m]$ '

else

    PS1='${debian_chroot:+($debian_chroot)}u@h:w033[1m`__git_ps1`033[0m$ '

fi



# If this is an xterm set the title to user@host:dir

case "$TERM" in

xterm*|rxvt*)

    PS1="[e]0;${debian_chroot:+($debian_chroot)}u@h: wa]$PS1"

    ;;

*)
