[11/12] diffcore-pickaxe: mark unused parameters in pickaxe functions

Commit Message

We have a virtual pickaxe_fn for handling -G versus -S pickaxe options.
They need to take the same set of parameters, but of course they care
about different ones (e.g., a regex -G will never use a kwset).

Mark the unused ones to appease -Wunused-parameter.
