This breaks the oid/sha1 barrier?

I would have expected the caller to do a

  oid_array_append_oid(&array, sha1_to_oid(sha1));

with sha1_to_oid working off some static memory, such that the
call to oid_array_append_oid (which we have as oid_array_append)
is just as cheap?

Could you say more in the commit message on why we collude
sha1 and oids here?
