#5 --search-keys method is missing

[Todd Vierling]

pgpenvelope (http://pgpenvelope.sourceforge.net/) uses
recv_keys() to search for keys on a keyserver, but this
doesn't work at all with servers that differentiate
keyid lookups from plaintext searches (e.g. pgp.mit.edu).

A search_keys() method corresponding to --search-keys
is needed.

Patch used by NetBSD pkgsrc-wip to implement search_keys()

I've attached a patch to implement this.

Note that there is a bug in gnupg itself, being tracked
under PR gnupg/199, that deals with --search-keys not
outputting the list of keys found in the search if stdout is
not a tty. Use of the new search_keys() function will
depend on that bug being fixed.

gnupg bug 199 was fixed in gnupg-1.2.3; therefore the
attached patch to implement search_keys() is now usable.
