difference in key import counting between GnuPG 1.4 and 2.1

[Daniel Kahn Gillmor]

Hi folks--

GnuPG 2.1 seems to count files differently when doing imports than 1.4.

Consider the comparison below (using the attached files, taken from
pygpgme/tests/keys).  In particular, note stats starting at "total
number processed:" and ending at "secret keys imported:"

I believe that gpg 2.1 is counting some of the keys multiple times (once
per subkey?) , but (for example), i'm not sure why it would claim 3
secret keys read and 2 secret keys imported, while 1.4 just say 1 in
each category.

This is one of the causes of test suite failure for pygpgme, because
pygpgme expects the values produced by 1.4.x (and presumably by 2.0.x,
though i haven't tested it).

Any pointers on how this should be resolved?  If they're "both right"
due to architectural differences, then i might just try to tune the
pygpgme test suite to ignore the differences.
