The sslv3 "support" is just the "gnutls-cli --x509cafile %t -p %p %h
--protocols ssl3" entry in the default value for tls-program, right?  I
think removing it wouldn't really be removing the feature as such, just
making the default "safer".  People who know what they are doing can
still customize with the appropriate value to get sslv3 if they want.

Hmm, and it looks like my version of gnutls-cli (3.5.8) doesn't even
support the --protocols switch anyway.

Oops.  Not sure what I was actually aiming for there.  I rewrote like
this:

** The tls.el and starttls.el libraries are now marked obsolete.
Use of builtin libgnutls based functionality (described in the Emacs
GnuTLS manual) is recommended instead.
