That should probably work, yeah. In that case we'd have to rename
`init_hash_algo()`, e.g. to something like `cl_setup_hash_algo()`, to
clearly show that it is part of the clar testing framework. I think
having a common prefix for such helper functions would be good anyway so
that the symbols never conflict with symbols we have in libgit.
