In Mathematica 9.0.1, I want to write a user-defined template for a function that I wrote: myfunc

Remove[myfunc]
myfunc::usage = "myfunc[x,y,z] is a function.
                 myfunc[x,y,z,w] is another function."

with the result:

As you can see, within the description myfunc is (in my opinion) unnecessarily repeated. In fact, templates for built-in functions do not behave that way. For example, look at the template for the Integrate function:

The function name Integrate is not repeated in the description. How do I tell Mathematica not to repeat the name of the function inside the description?
