Use $variable:t to get the tail (the name after the last "/") and use
$variable:h to get the head (everything before the last "/").

alias cd    'cd \!*; set cwdh=$cwd:h; set prompt="($cwdh:t/$cwd:t) $myprompt"'
alias pushd 'pushd \!*; cd .'
alias popd  'popd \!*; cd .'

Or go read the Frequently Asked Questions posting in the "newuser" and
"announce" newsgroups.
