Not able to support all of the git object

[catatsuy]

The commit id d9bb4be · git/git warn "unknown header ''" when I use this gem on git/git.

It is the unexpected implementation of Grit::GitRuby::Commit::from_raw in grit/lib/grit/git-ruby/git_object.rb .

require "grit"

GIT_REPO = '../git'

repo_grit   = Grit::Repo.new(GIT_REPO)
repo_grit.commit('d9bb4be53bc5185244b4be986')

output:
