This code as a lot of rough edges, in particular it relies on a well
behaving keyboxd. We need to add code to shutdown the datastream
reader thread in case of errors and to properly get it up again. We
also need to make really sure that both threads run in lockstep so
that the datastream thread is only active while we are sending a
command to the keyboxd.
We should also see whether we can depend nPth initialization on the
--use-keyboxd option to avoid any problems with nPth.
And we need to test on Windows.

--
These search modes were added over time and there has until recently
be no incentive to remove the cruft. With the change for v5 keys I
finally went over all places and allowed the generic fingerprint mode
along with a given length of the fingerprint at all places.
Consequently the other modes can now be removed.

This prepares the support for OpenPGP v5 keys. The new version 2 blob

opportunity to prepare for storing the keygrip in the blob for faster
lookup by keygrip. Right now this is not yet functional.

* common/ttyio.c (do_get): Re-indent and remove the checking for char

--
The code is really old (mid 1998) and with the checking for 0xa0 it
has an implicit assumption of utf-8 or latin-1. Worse, the check was
for c > 0xa0 and not c == 0xa0 so it never worked as intended.

2697 were left which seem to be valid sub-addresses.
To filter mailboxes out from a line delimited list with
user-ids (e.g. an SQL output), the command
t-mbox-util --verbose --filter
can be used; to output w/o sub-addresses add --no-sub.

When gpg was invoked by a Perl web application on FreeBSD, fstat in

lighter than fstat, it works fine. Since uur purpose is to check if
file descriptor is valid or not, lighter operation is better.
