osx - Set the title for bash Terminal on mac OS X to current working directory

I know they have been asking a lot of this question and I got it worked perfectly, but one thing I don't understand is why this is different.
#This will show the full path (/usr/bin)
PROMPT_COMMAND='echo -ne "\033]0;${PWD}\007"'
#This will set to the directory name only (bin)
PROMPT_COMMAND='echo -ne "\033]0;${PWD##*/}\007"'
The problem I have here is that I want to use the second one, but when I open a new tap it will go back to the default working directory, whereas the first one will keep the same working directory if I open another tap which I want that.

Strange. Maybe it has to do with when the pattern-expansion takes place in bash's order of processing.
Something like `PROMPT_COMMAND='BASED=${PWD##*/} echo -ne "\033]0;$BASED\007"' might do the trick.
EDIT: That didn't work? Maybe this will
set_prompt () {
BASE_PATH="${PWD##*/}"
echo -ne "\033]0;$BASE_PATH\007"
}
PROMPT_COMMAND=set_prompt

The way my bash prompt is currently configured, it shows the whole path to the current directory. This is annoying when I'm deep inside a directory tree, as the prompt becomes so long that every command wraps into the next line. How do I make it show only the last part of the path?
This is what I have in my .bashrc:
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*|rxvt*)
PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD/$HOME/~}\007"'
;;
*)
;;
esac
quack quixote
Change the \w (lowercase) to \W (uppercase):
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\W\[\033[00m\]\$ '

this one waaaaaay over here ------------------------------------------------+
Have a look at the Bash Prompt HOWTO for lots of fun details. example:
user@host:/usr/local/bin$ echo $PS1
${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\u@\h\[\033[00m\]:\[\033[01;36m\]\w\[\033[00m\]\$
user@host:/usr/local/bin$ export PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\u@\h\[\033[00m\]:\[\033[01;36m\]\W\[\033[00m\]\$ '
user@host:bin$
The PROMPT_COMMAND variable, if set, is a command that gets run before displaying the prompt specified in PS1. In your case, PROMPT_COMMAND runs an echo statement with certain ANSI escape sequences that manipulate the titlebar of an Xterm.
If you suspect your PROMPT_COMMAND is overriding your PS1 prompt, you can unset it and test things out:
$ unset PROMPT_COMMAND
Finally, be sure that you're changing the PS1 definition that actually gets used. Common locations are /etc/bash.bashrc, /etc/profile, ~/.bashrc, ~/.bash_profile, ~/.profile. The system files are generally (but not always) run before the user files.
