This reverts commit da560097c05612f8d360f86528f6213629b9c395.

It makes no difference as it was mistakenly thought that it fixes
a bug while another unnoticed change have been preserved in the
tester's repositorory.

Please include human readable descriptions of things like commits and
issues being discussed in e-mail in your mails, this makes them much
easier for humans to read especially when they have no internet access.
I do frequently catch up on my mail on flights or while otherwise
travelling so this is even more pressing for me than just being about
making things a bit easier to read.

Sure! But I will wait a bit (a couple of days?) to give a chance to
get this (re)tested.
