I also find it terrible.  Tho it is at least protected by a 3-way prompt
(tho only 1 rather than 5).

I think that will only push the problem elsewhere, which is "which file
name to use: .authinfo.gpg or .authinfo.spg".  It seems simpler to just
let the user configure the behavior she wants.  By default just use
symmetric encryption.
