Well, one of the subarguments here is whether we are going to change the
behavior of the table-related \d commands too.  If we choose a modifier
other than S for \df, I'd be inclined to adopt the same behavior for the
table commands.

[ shrug ]  But '-' has the correct implication that you're removing
something.  Those other symbols are just arbitrary.  I'd like to pick
something with at least some mnemonic value.
