Title: Function has more clauses
Goal: Reorder function arguments named `foo/2' when the second clause is marked based on the new order `[2,1]'.
Parameters: [{file,test3.erl},{position,49}, {order,[2,1]}].
Documentation: In this test case, the parameter of the function `foo/2'
 are to be reordered based on the list given. The first and the second
 parameters swap. In the calling place of the function the parameters
 are reordered too. Interestingly, the second clause of the 
 function is marked. The transformation can be executed. The cursor is 
 on "foo({X,Z},no)".
