"info setsector" claims you "can change anything that appears in dump
or peek (I think)", which has always been wrong.
edit is much more complete. However, edit used to be more limited in
that it could change only one sector. For mass-changes, you had to
use setsector and setresource. Since that limitation is gone, there's
no real use left for setsector and setresource.
