Removing old preferences from exported key

[Johan Wevers]

Hallo,

I changed the preferences for my gpg key to add the new Camelia ciphers
and move IDEA more backward as I got problems with people with old pgp
keys using old gnupg versions claiming they supported it but actually
didn't support it.

However, when I export the key it now contains both preference
signatures. I did export it with

export-options export-clean-sigs export-clean-uids

in gpg.conf.

How do I export it removing the first preference signature?
