Having a way to see the output of gpgtar is often useful for

common.conf was read.

Note that this works only if --assume-binary is given. The use case
for the feature is PDF signature checking where the PDF specs require
that the detached signature is padded with zeroes.
* common/openpgp-oid.c (oidtable): Add them.

(openpgp_oidbuf_is_ed25519): Take new OID in account.
(openpgp_oidbuf_is_cv25519): Ditto.
--
ed25519 is used in GnuPG and other implementations since 2015 and thus
we can't simply switch to the shorter OIDs. However, we have not
widely used them with v5 keys (only ed448 forced the use of v5) and
thus it might be possible to use the new OIDs with v5 keys.
Note that Libgcrypt supports the new OIDs even in 1.8.
* common/name-value.c (nvc_get_boolean): Rewrite.
--
The function may now return a positive or negative number instead of
just 1 for true. All callers were already prepared for this.

* g10/options.h (opt): Remove override_compliance_check.
* g10/sig-check.c (check_key_verify_compliance): Remove use of that
option.
--
The introduction of --override-compliance-check actually hid the real
cause for the signature verification problem in de-vs mode for the
Ed25519 key. The real fix is to handle the EdDSA algorithm in
gnupg_pk_is_allowed.

This fixes a bug with user ids with leading spaces because:
wks-client lists all mail addresses from the key and matches them to the
requested mail address.
If there are several user-ids all with the same mail address
wks-client picks one of them and then extracts exactly that user id.
However, here it does not match by the mail address but by the full
user-id so that we can be sure that there will be only one user-id in
the final key.
The filter built expression unfortunately strips leading blanks but
requires a verbatim match. Thus it won't find the user id again and
errors out.
The new -t flag and a non-trimming strtokenize solves the problem.

That is actually a more correct directory than APPDATA. This fixes

LOCAL_APPDATA is expected to be on the local box and thus in the
