The reason I did it this way was because earlier, Junio said:

So I opted to write the tests in a way where a tmp file won't be
produced. This pattern was shamelessly stolen from
'set up mod-256 conflict scenario' in t7600 where it does the following:
# 256 near-identical stanzas...
for i in $(test_seq 1 256); do
for j in 1 2 3 4 5; do
echo $i-$j
done
done >file &&
git add file &&
git commit -m base &&
# one side changes the first line of each to "master"
sed s/-1/-master/ <file >tmp &&
mv tmp file &&
git commit -am master &&
Good point about the heads and seds, though. I completely forgot that
they accept a file argument.

Will do.
