Hello

This is more a feature request than a bugreport. The problem is as follows:
whena updated version of a public key, with new UIDs, is imported, there ar=
en't
corresponding UIDs added to the private key. Example:

Subshell:alex@syjon:[~]:5:> gpg -k alex@sword

pub  1024D/21939169 1997-09-24 Janusz A. Urbanowicz <alex@bofh.net.pl>
uid                            Janusz A. Urbanowicz <alex@bofh.org.pl>
uid                            Janusz A. Urbanowicz <alex@bofh.torun.pl>

ber.org>
uid                            Janusz A. Urbanowicz <alex@hell.pl>
uid                            Janusz A. Urbanowicz (ICM) <alex@icm.edu.pl>

Subshell:alex@syjon:[~]:1:> gpg --list-secret-keys

Secret key shows two revoked UIDs (alex@sword & alex@eris) while it lacks
two UIDs imported later - it is impossible to select signing key by one of
the missing UIDs:

Subshell:alex@syjon:[~]:6:> gpg -u alex@bofh.net.pl --detach-sign foo
gpg: skipped =01lex@bofh.net.pl': secret key not available
gpg: signing failed: secret key not available

There are two possible solutions: adding UIDs to secret key as they are
meged into public key (this is how PGP 2 did it), or use indirect lookup of
the secret key - find long key id corresponding to given UID in public keys,
and then find the secret key of given key ID.
