Because it is not new commit at all. Christoph's patch was introduced
10 releases before.

$ git describe bc3e53f682
v3.1-7235-gbc3e53f

If we just revert it, we may get another and opposite regression
report. I'm worried
about it. Moreover, I don't think discussion better fix is too difficult for us.
