Do not print a function's arguments?



Dear all,

I have a function

(%i1) u : u(x);

hence, 

(%i2) derivabbrev: true$
(%i3) diff(u,x);

gives (_ denotes subscript)

(%o3) u(x)_x

Is there a way to make Maxima print

u_x

instead? I.e., to omit the function's arguments for clarity?


Cheers,
Thomas
