Use the ZERO_OID variable to express the all-zeros object ID so that it
works with hash algorithms of all sizes.

Nothing wrong with the patch.
There is, however, a trick in t0027 to transform the different IDs back to a bunch of '0'.
The content of the file use only uppercase letters, and all lowercase ad digits
are converted like this:

compare_ws_file () {
	pfx=$1
	exp=$2.expect
	act=$pfx.actual.$3
	tr '\015\000abcdef0123456789' QN00000000000000000 <"$2" >"$exp" &&
	tr '\015\000abcdef0123456789' QN00000000000000000 <"$3" >"$act" &&
	test_cmp "$exp" "$act" &&
	rm "$exp" "$act"
}

In the long term the 'tr' may need an additional 'sed' expression.
