I didn't say that empty keyfile can be used as real passphrase (in luksFormat),
but the verification (luksOpen) will fail with "No key available with this passphrase"
and with the patch it fails with different error - error during reading key.

I can imagine that some scripts can depend on this behaviour and
there is no real need to change it.
When you enter empty string from terminal, it does the same.
