Here's a trick I stumbled across while setting up my own
version of this a while back.
Try typing:
dirs
If the directories that it reports are always in the form
you want (on my Apollo, ~ is displayed instead of the long
pathname to my home directory), you can eliminate sed from
the pipeline in setprompt by using dirs instead of pwd as
the starting point.
Example:
alias setprompt \
'set noglob;set d=(`dirs`);set prompt="$d[1] % ";unset noglob'
