"align:$option" seems right, will change.

After reading this and Junio's detailed description stating otherwise.
It's safe to
go with something similar to what Junio suggested :
for option in ...
do
test_expect_success "align:$option" '
git for-each-ref --format="...$option..." &&
...
'
done

Thanks.

Maybe an independent patch post this series. I'll keep a note to myself.
