Here's a little sed alias which trims the directories in a "dirs" listing to
the last two names (if there are more):

    alias trim   "sed -e 's=~*/[^ ]*/\([^ /]*/[^ /]*\)=...\1=g'"

so you could say:

    set prompt = `hostname`[\!]`dirs | trim`

note that it leaves all the directory elements in - you may want to strip out
all but the first (current).  I leave that as an exercise for the reader...
I use it to set up a label for my sun shelltool windows.
