Figuring out the ShortIntegers test is a challenge, because the chromium tests
hand build their own asn.1-encoded private key, and only produce a single bit
of information for the tests:  it equals the expected value, or it doesn't.  It
doesn't say where the difference lies.

The expected output is easy enough to see, short_integer_with_high_bit in
rsa_private_key_unittest.cc.  The value it's compared to isn't produced
directly by Wine, however.  Instead, a private key is exported in a different
format, and the unit tests copy bits of pieces of this into a memory blob,
along with magic asn.1 bytes.  Aside from the CryptExportKey, whose value is
not the final output value, none of the remaining code to produce the expected
output value uses the crypto API, so a trace isn't helpful.

The relevant code is in rsa_private_key.cc's PrivateKeyInfoCode::Export
function.

A simpler to understand bit of code would go a long way toward getting this
fixed.  Ideally it'd be a Wine regression test.  I tried compiling this myself
under Linux with wineg++, but I couldn't coerce it.
