Subject: [PATCH 02/24] t9300 (fast-import): avoid hard-coded object names

From: Jonathan Nieder <[email-masked]>
Date: Fri, 24 Sep 2010 02:05:10 -0500

compare_diff_raw already ensures most (though not all) of the tests
do not rely on any particular hash function, but still the attentive
reader might be comforted by some less opaque object descriptions.

Tested with

	sed -i s/compare_diff_raw/test_cmp/g t9300-fast-import.sh &&
	sh t9300-fast-import.sh -v -i
