`git.sv.gnu.org' and `git.savannah.gnu.org' are the same thing,
according to `dig':

    $ diff =(dig git.sv.gnu.org) =(dig git.savannah.gnu.org) # zsh 
output-to-file syntax (`=') used if you're curious.

Which indicates that the IP addresses are the same.

`sv.gnu.org' is (probably) only used as a shorthand for
`savannah.gnu.org' literally only for convenience. If there is in fact
a different I'd be very interested to here about it.

For more proof I cloned both repositories and measured the directory
sizes:

    $ du -s savannah.gnu.org sv.gnu
    72116   savannah.gnu.org
    72120   sv.gnu

Where the host name of where I cloned it from (which is stored in
`.git.config') is probably the only thing making a difference.
