Document the wipe features of Disks
Disks in Jessie now advertise a wipe feature. When you create a new partition it proposes to "overwrite exisiting data with zeroes".
We should investigate how does this work and how does it do compared to "wipe available disk space" in relation with #7118.

When you create a new partition it proposes to "overwrite exisiting data with zeroes".
In udisks2 2.1.6-2 (current sid, while Jessie has 2.1.3-5), the code lives in the
erase_device function, in
src/udiskslinuxblock.c, in udisks2 source code. See also
populate_erase_combobox in gnome-disk-utility source code. Apparently, ATA erasure feature can be displayed if the drive supports it. The "with zeroes" feature does just what it says.
What other info do you need?

All-right, let's do that. But not for the release as it's not a regression :)
That might fix #5323 but needs to be checked.
