  object: return GIT_EINVALID on parse errors Return `GIT_EINVALID` on parse errors so that direct callers of parse functions can determine when there was a failure to parse the object. The object parser functions will swallow this error code to prevent it from propagating down the chain to end-users. (`git_merge` should not return `GIT_EINVALID` when a commit it tries to look up is not valid, this would be too vague to be useful.) The only public function that this affects is `git_signature_from_buffer`, which is now documented as returning `GIT_EINVALID` when appropriate.
