Hmm, "transitional" has the same problem...  I see that "extra" for
"Extra Forward Secrecy" and "efs" isn't bad, if we removed extra
symmetric keys maybe it would be more clear.  However if we're going
to use "f" for the token and variable names, it would be nice to have
something that matches that, but "extra" and "f" clash with
"ephemeral" and "e".

What do you think about "Further Forward Secrecy", "ffs" for the
pattern transformation, and *_FFS for the pseudocode names?
