It should not be difficult to adapt Dave Vehrs' prompt_workingdir
function, found in a longer script at
http://www.debian-administration.org/articles/205

The function trims to pwdmaxlen, which you can adjust from the current
1/4 window width, and prefixes "...", which seems neat. Anyway, handed
that for a start, the world is your oyster. ;-)

He also changes colours when $cwd is not writable, and after su, with
gradated privilege indication. (For me, $ and # have long sufficed, but
it might be worth considering.)
