# ksh-style "cd old new" for bash
# "ccd old new" replaces old with new throughout $PWD and then tries
# to cd to the new path
#
# This works very well for eg $HOME/mmt/2010/compsci2/grades ->
# $HOME/mmt/2010/compsci3/grades which I have to do constantly
#
# Shamelessly stolen from Learning the Bash Shell (3ed), Cameron Newham
# & Bill Rosenblatt
