Think of defvar as defining a variable.  If the variable is already
defined, there's nothing for defvar to do.  Setting the variable's
default value likewise only affects it's current value if there *is*
no current value.  (That's why defvar *does* set the global "default"
if that's unset, even if there's a buffer-local variable with the same
name.)
