Revision e885a84f1bc660adfc1dea5f6c25d0a92c7c9dbc authored by Jeff King on 30 September 2020, 12:28:18 UTC, committed by Junio C Hamano on 30 September 2020, 19:53:47 UTC
Many functions take an argv/argc pair, but never actually look at argc. This makes it useless at best (we use the NULL sentinel in argv to find the end of the array), and misleading at worst (what happens if the argc count does not match the argv NULL?). In each of these instances, the argv NULL does match the argc count, so there are no bugs here. But let's tighten the interfaces to make it harder to get wrong (and to reduce some -Wunused-parameter complaints).
