Avoid excessive escaping for rsync special remotes that are not accessed over ssh.
This is actually tricky, 45bbf210a1210172c7c7b87879ed74f7c8ccbdba added
the escaping because it's needed for rsync that does go over ssh.
So I had to detect whether the remote's rsync url will use ssh or not,
and vary the escaping.
