Gpgtools MacGPG2 → 2.2.17

Currently Some keyservers do not behave like others when it gets to listing keys with fingerprints.

dirmngr currently doesn't add "fingerprint=on", nor has it an options to set it manually for a request.

Expected Most servers return a list including fingerprints, but some only respond with key-ids.

This can be reproduced using the following request:
/pks/lookup?op=vindex&options=mr&search=GPGTools%20Team

When "fingerprint=on" is added to the request, all tested keyservers return the fingerprints – which would be preferable.

Here are two keyservers to test, which are both part of the sks-keyservers.net pool:
"normal" behavior:        pgpkeys.uk (192.146.137.98) sends key-id be default:  pgpkeys.hu (37.17.173.9)

Here is the required patch for dirmngr (patch by mento@gpgtools.org):

Thanks for considering adding this.
