I want the .gpg file first because I really want to push people towards
encrypting sensitive data.  Otherwise that's fine and a trivial change
and I'll make it soon.

I don't think auth-source.el should undertake that kind of monitoring.
It's annoying and, when incorrect, *very* annoying.

It will do an extra fopen() every time something can't be found, even
when .netrc doesn't exist, so it definitely affects people.  I will add
.netrc because it's sensible but I don't like so many file searches.
