test-mergesort: mark unused parameters in trivial callback

peff · gitster · commit f288a57789b6 · 2024-08-17T09:46:23.000-07:00
The mode_copy() function does nothing, but since it's used as a function
pointer within "struct mode", it has to conform to the interface. Mark
it to quiet -Wunused-parameter.
