Symmetric cipher selection order, RSA keys

[Steve Butler]

Would it be an ordered list so that the left most item left in the
intersection would take precedence?  That way if my personal list was:
CAST5, AES256, AES, 3DES  then CAST5 would be picked (based on the two below
keys).  However, if I listed AES256, AES, CAST5, 3DES then AES would be
picked.

After thinking about this some more, I think that a list of algorithms
that the user favors is a good idea.  I've added
"--personal-preference-list" to the CVS.  GnuPG will take this list
into account when picking algorithms.
