pgp -c,no initialization vector, possible bug, pgp 26ui

[Derek Atkins]

I don't know if this will cause a problem or not, but PGP 2.6 defines
ideakey[24] in idea_encryptfile().  So, it may be a problem in 2.6ui;
I'm not sure.  I don't know the IDEA code well enough to determine,
and I don't feel like tracking this down right now -- it's not a
factor in 2.6.
