I assume you mean with this that gpg should read from fd 0 and write to 
fd 1, IOW, it should use the standard channels. If I am right, then the 
memset above has initialized gpg as needed already. Then gpg.argv is the 
only thing you are setting up in struct child_process gpg; but in this 
case you can use a convenience function...

... here (note: no struct child_process needed):

	if (run_command_v_opt(args, 0)) {

(Just in case this patch is required...)
