The problem here was that future-default gives the primary and subkey
algorithm. However, when using future-default for adding a key, the
second part was always used which is for encryption. If the caller
now wanted to create a signing subkey using the future-default
parameters this did not worked.
gpg --batch --passphrase "" --quick-add-key FPR future-default encr
aready worked as did
gpg --batch --passphrase "" --quick-add-key FPR ed25519 sign
but
gpg --batch --passphrase "" --quick-add-key FPR future-default sign
does only work with this fix.

* g10/keygen.c (keygen_set_std_prefs): when producing default internal
personal-digest-preferences, keep the same order. When publishing
external preferences, state preference for SHA512 first.
--
SHA-512 has a wider security margin than SHA-256. It is also slightly
faster on most of the architectures on which GnuPG runs today. New
keys should publish defaults that indicate we prefer the stronger,
more performant digest.
Specifically, this changes --default-preference-list from:
SHA256 SHA384 SHA512 SHA224
to:
SHA512 SHA384 SHA256 SHA224
This patch deliberately avoids touching --personal-digest-preferences
(which itself would affect the default of --digest-algo and
--cert-digest-algo), so that public-facing cleartext signatures and
identity certifications will continue to be made with SHA256 by
default.

--
Backport from master commit:
ccf3ba92087e79abdeaa0208795829b431c6f201
To sanitize a regular expression, quoting by backslash should be only
done for defined characters. POSIX defines 12 characters including
dot and backslash.
Quoting other characters is wrong, in two ways; It may build an
operator like: \b, \s, \w when using GNU library. Case ignored match
doesn't work, because quoting lower letter means literally and no
much to upper letter.

* g10/card-util.c (factory_reset): Simplify.
--
In this summer, I got report about old code before this change didn't
work with newer Yubikey. I got another report test version of OpenPGP
card V3.3 implementation didn't work, either. Then, I confirmed that
according to the OpenPGP card specification, the procedure of old code
is not expected by its author.
This change simplify "factory-reset" as simple.
Only versions of Gnuk 1.2.2, 1.2.3, 1.2.4, won't work with this
change. That's because the factory-reset feature of Gnuk was
introduced by reading the implementation of GnuPG, instead of reading
the specification. Gnuk 1.2.5 and later works well. All OpenPGPcard
implementations I have work well (2.0, 2.1, 2.2, test version of 3).

This is a partial reversion of
7e1fe791d188b078398bf83c9af992cb1bd2a4b3. Werner and i discussed it
earlier today, and came to the conclusion that:
* the risk of metadata leakage represented by a default
--auto-key-retrieve, both in e-mail (as a "web bug") and in other
contexts where GnuPG is used to verified signatures, is quite high.
* the advantages of --auto-key-retrieve (in terms of signature
verification) can sometimes be achieved in other ways, such as when
a signed message includes a copy of its own key.
* when those other ways are not useful, a graphical, user-facing
application can still offer the user the opportunity to choose to
fetch the key; or it can apply its own policy about when to set
--auto-key-retrieve, without needing to affect the defaults.
Note that --auto-key-retrieve is specifically about signature
verification. Decisions about how and whether to look up a key during
message encryption are governed by --auto-key-locate. This change
does not touch the --auto-key-locate default of "local,wkd". The user
deliberately asking gpg to encrypt to an e-mail address is a different
scenario than having an incoming e-mail trigger a potentially unique
network request.
