Yeah. All of the \d commands are compromises between verbosity and
displaying all needful information, so I don't think that Robert's
proposed approach is particularly helpful. It would only lead to
requests for \d-plus-one-half mode once people realized that "everything"
is too much. (I'd rather go in the direction of \d++ yielding extra
info, if we ever decide to have more than two verbosity levels.)
I do think there's some merit to the argument about "it's been like
this for years, why change it?". But if you reject backwards
compatibility as an overriding factor here, the currently-proposed
patch seems the sanest design to me.
