Possible GPGME bug

[Adam Schreiber]

In fixing a bug in Seahorse, I found that our feature to revoke a sub
key was no longer working.  It uses the gpgme_op_edit API.  I checked
the challenge and responses of gpg --edit-key manually and found that
they matched those our state machine expected.  The responses of
gpgme_op_edit are different.  I will paste the relevant output of
running each below.  I am running gpg 1.4.7 and GPGME 1.1.4.

Cheers,

Adam Schreiber
