Er, ... yeah, it works for my bash and (up-to-date) dash too!

Yes, this fixes the problem and does not introduce a regression.

So, the patch is correct, but (apart from the last sentence) the
commit message is *absolute rubbish*. I won't bore you with the

However, I much prefer Jonathan's patch which removes this test
