Once you've had exposure to udev you soon learn that "wondering why" gets
you nowhere:)  However bizarre, your only option is to conform.
Name mangling in lvm2/device-mapper was designed both to conform and
to still allow for all possibilities in as transparent a way as we could.

The primary new limitation is a reduction in the effective maximum length
of a device name due to the quoting.  If this becomes a problem we will have
to extend the kernal API to support longer names.
