No, at least not in Debian's configuration files. It's most likely an
artifact of their mail user agent.
Debian's /etc/skel/.bashrc contains these lines:
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:\w\$ '
fi
The leading \[\e]0... part appears to be a local addition.
