Details:
When running "git pull" on a git repository on Savannah, I got an error
message
Warning: the ECDSA host key for 'git.sv.gnu.org' differs from the key for the
IP address '208.118.235.201'
Offending key for IP in /home/g/.ssh/known_hosts:26
Matching host key in /home/g/.ssh/known_hosts:23
Line 26 is 208.118.235.201 ssh-rsa

If I go and remove that key from the known_hosts file, "git pull" then prints
Warning: Permanently added the ECDSA host key for IP address '208.118.235.201'
to the list of known hosts.
the first time. The line it adds to known_hosts is
208.118.235.201 ecdsa-sha2-nistp256

On subsequent tries, it completes without error.
However, then when I try to update an SVN repository on Savannah with "svn
update" I get an warning:
$ svn update
Updating '.':
Warning: the RSA host key for 'svn.savannah.gnu.org' differs from the key for
the IP address '208.118.235.201'

Are you sure you want to continue connecting (yes/no)?
It's complaining about the line that was just added by "git pull". It does
this every time svn runs.
How can I set it up so that both "svn update" and "git pull" work correctly,
without printing a warning or prompting for confirmation?
