I tried to get rid of them with 'gpg --edit-key' (which automatically
moved the signatures to a UID on the primary key), but --send-keys and
--recv-keys caused them to be added right back. Repeating this procedure
moved the signatures again so that the UID in question now has two
copies of each of these signatures at the end of its signature list.
In other words, it looks like any time I go through an --edit-key /
--send-keys / --recv-keys cycle (however extended), I'm going to grow
six new signatures on my key. Could GnuPG be fixed to check for
duplicates before it moves signatures? The delsig UI is going to be
extremely tedious for getting rid of these and of course won't affect
