I've tried the current version (0.27) that uses ~/.netrc in
nntp-send-authinfo, and we need a syntax for excluding machines from
password sending.  Either we don't send authinfo to machines not found
in the ~/.netrc or ~/.authinforc (or whatever) file or we put in
machine names without any password or user name.

I prefer the first approach.
