OK, I fixed this in a better way (r102771).

My test case is:

$ mv .gnupg .gnupg.bak
$ gpg --gen-key # create a key foo <at> example.com
$ gpg --gen-key # create a key bar <at> example.com
$ gpg --gen-key # create a key baz <at> example.com
$ gpg --edit-key foo <at> example.com # revoke foo <at> example.com
$ gpg --delete-secret-key bar <at> example.com

(mml2015-epg-find-usable-secret-key
  (epg-make-context 'OpenPGP) "foo <at> example.com" 'sign)
=> nil
(mml2015-epg-find-usable-secret-key
  (epg-make-context 'OpenPGP) "bar <at> example.com" 'sign)
=> nil
(mml2015-epg-find-usable-secret-key
  (epg-make-context 'OpenPGP) "baz <at> example.com" 'sign)
=> (epg-key . ...)
