Here we see the same pattern again, but this time the @@ lines give
better context: these are actually hash I/O. Maybe it's about time we
add
int oidwrite(char *, size_t , const struct object_id *);
// optionally, void strbuf_addoid(struct strbuf *, const struct object_id *);
int oidread(struct object_id *, const char *, size_t);
for conversion from between an object_id in memory and on disk? It
would probably be a straight memcpy for all hash algorithms so we
don't really need new function pointers in git_hash_algo for this.
