The `--short=` option for git-rev-parse(1) allows the user to specify to how many characters object IDs should be shortened to. The option is broken though for SHA256 repositories because we set the maximum allowed hash size to `the_hash_algo->hexsz` before we have even set up the repo. Consequently, `the_hash_algo` will always be SHA1 and thus we truncate every hash after at most 40 characters. Fix this by accessing `the_hash_algo` only after we have set up the repo.
