For what it's worth, I'm attaching a patch for GnuPG and its counterpart
for GPGME.  With the patch, gpg emits an ERROR status line with
"delete_key.secret" error source (the name is taken from the cpr prompt
on the above line in the code).

I'm currently working on Seahorse visual refresh[1] in GNOME, and to
provide a responsive UI, I want this and the --gen-key cancellation
issue to be fixed.
