Hello, this fails:

	(faui00u) [~/work/git/yagf] git-diff-tree -z HEAD | git-diff-helper -z
	03c70739ae572ea9832b97dfcf9ca2594702efe8 (from 30e756ea8569bb429b7073b304acd8a960f77e4b)

But:

	(faui00u) [~/work/git/yagf] git-diff-tree -z HEAD 30e756ea8569bb429b7073b304acd8a960f77e4b | git-diff-helper -z

		} else {

works? What I am doing wrong here?
