Sorry, it didn't occur to me that that would impinge on what you
were doing over here ... though in retrospect I should have thought
of it.

Well, \dconfig needs it because it would like to get processed
as just a name. But I think it's a bug fix because as things stood,
if the caller doesn't provide a schemavar and the pattern contains a
dot, the code just silently throws away the dot and all to the left.
That doesn't seem very sane, even if it is a longstanding behavior.
