Patch for PR gnupg/199

[Todd Vierling]

I replied to GNATS, but it doesn't seem that my reply made it there.  Note
that I am *NOT* on this list; please include me in Cc: in responses.

In the PR, use of --search-keys in a "PGP/GPG frontend" (pgpenvelope,
GnuPG::Interface) is useless because the non-tty stdout default is
block-buffered rather than line-buffered.  Thus the key list, which is
written to stdout, may never show up until entering (Q)uit.

The following patch adds a fflush(stdout) to ensure that the list of keys in
--search-keys is flushed to stdout before writing the prompt to the user.
(BTW, I'd really like to see this in 1.2.3 as well, if possible.  8-)
