Hopefully, this whole thing can go away at some point.  This flush is
to support external programs reading and displaying the keyserver
search list, but the format of the list is not fixed and is already
very different in 1.3.x.  Programs should use the --with-colons
format, but unfortunately there is no --with-colons --search-keys menu
in 1.2.x (there is in 1.3.x.).

It would work fine to display the exact text GnuPG outputs, but any
program that tries to actually parse the search list is going to break
when 1.4 comes out.

Possibly the answer is to backport the --with-colons --search-keys to
1.2.x (it's minor).
