Regarding this point, I kind of think that \dconfig is a break with
established precedent, but in a good way. Previous additions have
generally tried to pick some vaguely mnemonic sequence of letters that
somehow corresponds to what's being listed, but you have to be pretty
hard-core to remember what \db and \dAc and \drds do. \dconfig is
probably easier to remember.
