mkswap(8) zaps the begin of the device (1024 bytes) only. This is not

wipefs: improve -a, use blkid_do_wipe()

Some filesystems (e.g. FAT) is possible to detect in many ways -- for
example if a magic string is stored on more places on the device. The
current implementation always removes from the device only the firstly
detected possibility.
