I forgot to cite the information I got from the cryptsetup maintainer.
The current state is documented in #548988.

1.0.7 have CRYPT-$UUID for luks devices. 1.1, which is supposed to be
released shortly, will have CRYPT-PLAIN-* and CRYPT-LUKS-*.

I'm still not fully aware what you are really trying to detect. The code 
is so full of comments in the relevant section, this makes it not easier  
to give comments.

I see three possibilities:
- Destinguish between uncrypted and crypted devices (the luks
  description would be wrong then).
- Destinguish between plain crypted and luks crypted devices.
- Destinguish between luks crypted and anything else.

The last looks like the correct one according to the names and checks.
The correct check for this one would be:
CRYPT-[0-9a-f]* || CRYPT-LUKS-*
The check for temporary-cryptsetup-* can go then. This will catch
anything from cryptsetup 1.0.7 up.

It makes no sense to comment on the actual check if I don't know what it
should do.
