argv.h: usage screen generator: remove the paradigm-supporting implementation.
The idea was nice, the functionality was helpful for development, yet the resulting layout and overall appearance were rather awful. Regardless of the effort that was put into this sophisticated flavor of the usage screen generator, and despite it's utility for debugging, it is now being replaced with a simpler, two-field-only variant.
