axis.m: Fix regression when accepting input handle (cset 5032ac119d52). * axis.m: When setting xlim, ylim, zlim to numeric values the functions must be called with the desired axis handle so that id doesn't always operate on gca.

function x = varg_nest (varargin)
  x = abs (f (-5)) + g;

  function x = f (varargin)
    x = abs (varargin{1});
  endfunction

  function x = g
    x = abs (varargin{1});
  endfunction
endfunction
