This seems to be an early version

Well, I still like to delete the whole word occasionally, so having
both is useful. Just removing the / doesn't seem to handle paths with
spaces either, so /foobar/with\ spaces/in\ it gives
/foobar/with\ spaces/in\
/foobar/with\ spaces
which is very annoying when directories have 6 spaces in them :). As
for being overkill, I have the whole thing I pasted in a separate file
so it doesn't clutter up my .zshrc
