that wouldn't really be any different than if you implement the -r
option like so:
 - `addwrite /foo` would always append the path regardless of
existence already in the variable
 - `addwrite -r /foo` would remove exactly 1 occurence

so if you don't want to do push/pop, let's stick with just adding a -r
flag and implementing things as described above as it makes dev's
lives simpler.
