160cf64abc
Allows Repository_getitem, Repository_read(_raw), Repository_create_commit, Repository_create_tag and Object_read_raw to use short hex strings to lookup objects. Also test getting objects from Repository using prefixes, looking up commit trees and parents by hex prefix, and looking up tag targets by prefix. Also stop raising TypeError if passing a too-short hex prefix to the lookup functions, instead use ValueError.
