Subject: [PATCH] Reverting the patch from #3165, as it broke other behaviours.
 I left the original test commented out (note that that test came from #2702,
 which seems to have a problem in FreeBSD and Windows, but not in Linux).

I included a new test, to watch over the now-broken
behaviour, I took it from #3179.
