Looking in the diretory dtc is invoked from is not very useful behavior.

As part of the code reorganization to implement this, I removed the
uniquifying of name storage -- it seemed a rather dubious optimization
given likely usage, and some aspects of it would have been mildly awkward
to integrate with the new code.
