Re: [PATCH] tree-diff: remove the usage of the_hash_algo global

> emit_path() uses the global the_hash_algo even though a local repository is
> already available via struct diff_options *opt.
>
> Replace these uses with opt->repo->hash_algo. With no remaining reliance on
> global states in this file, drop the dependency on 'environment.h' and remove
> '#define USE_THE_REPOSITORY_VARIABLE'.

> This follows earlier cleanups to introduce opt->repo in tree-diff.c [1][2].
