Getting gpg (or is it pgg?) to play nice with proxy

[Niklas Morberg <niklas.morberg@axis.com>]

Inspired by Jesper Harder's info on how to automatically
verify inline gpg signatures I decided to have a go. I got
pretty much everything set up, except I can't get gpg to
fetch keys from a keyserver through a proxy.

If I do `M-x shell-command' and execute:

gpg --recv-keys 0x80808080

I get the reply:

gpg: requesting key 80808080 from search.keyserver.net
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

Which is fine since the key is invalid anyway. But if I try
to verify a signed message from within gnus the request
times out. I've tried to change the keyserver to a local one
inside the firewall and then it works. The local keyserver
only holds keys for local users, so it is not that useful
for me.

I've modified gpg.conf to use the http_proxy (and since it
works from a shell within emacs I guess it is properly set
up).

Some information that might be of help:

I'm running cygwin as my shell and unless I have:

(setq shell-command-switch "-ic")

the `M-x shell-command' also times out. It still works if I
run it in a shell in emacs (`M-x shell' and then the gpg
command.)
