connect: reject ssh hostname that begins with a dash
When commands like "git fetch" talk with ssh://$rest_of_URL/, the
code splits $rest_of_URL into components like host, port, etc., and
then spawns the underlying "ssh" program by formulating argv[] array
that has:

 - the path to ssh command taken from GIT_SSH_COMMAND, etc.

 - dashed options like '-batch' (for Tortoise), '-p <port>' as
   needed.

 - ssh_host, which is supposed to be the hostname parsed out of
   $rest_of_URL.

 - then the command to be run on the other side, e.g. git
   upload-pack.

If the ssh_host ends up getting '-<anything>', the argv[] that is
used to spawn the command becomes something like:

    { "ssh", "-p", "22", "-<anything>", "command", "to", "run", NULL }

which obviously is bogus, but depending on the actual value of
"<anything>", will make "ssh" parse and use it as an option.

Prevent this by forbidding ssh_host that begins with a "-".
