Consider adding SSHv2 public key fingerprints to www page

[Agustin Martin]

HI,

Just cloned new Emacs git repo. Big thanks to all people involved.

Seems I lost old info about RSA key, because when doing this I got

The authenticity of host 'git.sv.gnu.org (140.186.70.72)' can't be
established. RSA key fingerprint is
80:5a:b0:0c:ec:93:66:29:49:7e:04:2b:fd:ba:2c:d5.

I noticed that other projects explicitly mention the SSHv2 public
key fingerprints for the repos, see e.g.

http://savannah.gnu.org/arch/?group=garpd

(that is where I double-checked the fingerprint before acepting). 

May worth adding similar info to

http://savannah.gnu.org/git/?group=emacs

and point to it from

http://www.emacswiki.org/emacs/GitForEmacsDevs

Regards,
