There's more than one way to do it :-)
I never did understand why bash is so popular. Zsh is much more capable,
smaller and the same price.
OK, OK: (Improving on Tim Ayers' shot):

This is shorter, and *much* more efficient:
export PROMPT_COMMAND="perl
-e'\$_=\$ENV{PWD};s!/.*(?=/.*/)!...!s;print'"
.... or use zsh, of course :-)
