I prefer <commit>^0 in scripts, simply because it is shorter, works
with any version of Git that knows how to detach, even the ones
before --detach was introduced. I offhand do not recall which
between <commit>^0 and <commit>^{} came earlier, but in practice I
saw nobody write the latter, so Dscho's suggestion is definitely an
improvement.
I do also care about "git checkout --detach" to keep working
correctly, but as long as we have dedicated tests to ensure that,
we'd be fine. In the case of the test being discussed, we assume
either should work correctly and the point of the test is not about
ensuring that <commit>^0 or --detach works, so either is OK.
Anyway, thanks for a patch and a review.
