Signature notations?

[Luke Powell]

I recently had to revoke a uid and when I did I was asked to give a
short notation about why I was revoking it. I'm curious as to how one
views those notations. I tried using the following command:

gpg --list-sigs --list-options\
show-unusable-uids,show-notations,show-sig-subpackets 7b4abdb3

but I didn't have any luck. Does anybody know if those notations are
stored, and if so, how they can be read out?

Thanks,

Luke
