Simpler but incorrect:

 * if you have more keys than will fit on the command line (like I do)
   your method fails, that's one of the reasons xargs(1) exists

 * cut(1) is using column positions in the output which are not guarenteed
   to stay the same in future GnuPGP releases, that's why the
   --with-colons option exists

 * --fast-list-mode makes a HUGE time difference on my keyring, that's
   what it's there for

 * using grep and cut is two processes to awk's one


The only things that are not strictly necisary in my alias are the pass
through "sort -u" and the "-n 20" option to xargs.  I did the former
to remove duplicate keyid's, which there shouldn't be but I copied it
from another alias I had and it doesn't hurt.  I did the later because
I didn't want gpg holding the lock files for the entire time it was
updating, this way it gives it up briefly after after every twenty keys.
