Thinking about this a bit more, perhaps we would want a generic mechanism to give parameters to various %? placeholders. This is not limited to "I can do color but there is no mechanism for the user to tell me that I should do color" %H, %h and %d may want to say. An obvious and immediate example is that %h might want to be told how many hexdigits it should use.
