Some further info:
This feature is not present in NSD v3.
To make you even sleep better tonight, it is also not part of the entire
history of NSD v2 :-)
The last version that had this was NSD v1.
So what you have stumbled upon is leftover configure magic that should
have been removed ages ago (and will be gone in the next release).
