* g10/gpg.c (main): Call write_status_failure for all commands which
print an error message here.
--
This status line can be used similar to the error code returned by
commands send over the Assuan interface in gpgsm. We don't emit them
in gpgsm because there we already have that Assuan interface to return
proper error code. This change helps GPGME to return better error
codes.

I guess that is a left-over from an early attempt to output

the former --list-trust-path command. Sending it to stdout is
probably useful so we do this now only in debug mode.

Printing all zeroes for a PGP-2 (v3 key) fingerprint has the problem
that frontends (or the user) may use that fingerprint to lookup a key
and gpg will return all PGP2 keys. They may then show a different
PGP-2 key than the one actually used for a signature. This is worse
than displaying a weak fingerprint.

In the situation of corrupted .gnupg/ where only private subkey is
available but no corresponding public key of the subkey, the code
returned public primary key which caused mysterious error (for a
user). This fix detects an error earlier.

The card reader name by PC/SC service might include USB bus,
which varies (on some platform like GNU/Linux). Thus, it's
better to match partial string.
Original patch was submitted by anstein. I changed it to fallback to
the first reader if no match found.

Using header lines like
Name:[lf]
[space][lf]
[lf]
resulted in running into the "(s2 = strchr (delimiters2, *s)" branch
and inserting a new token for the empty continuation line. This also
led to one byte read after the string which is what Hanno figured.
The new code should handle empty continuation lines correct.
