a=openpgp; fpr=57CE4C7F6375710FCB65C6063ED59F248E468C7F The function `get_midx_filename_ext` uses `hash_to_hex` which internally uses the global variable `the_repository`. To remove this dependency, pass down the `hash_algo` to both `get_midx_filename` and `get_midx_filename_ext`. This adds `the_repository` variable usage to `midx-write.c`, which will be resolved in a future commit.
