    Function Wizard: don't overwrite an unlisted function
    
    * in a spreadsheet cell enter =LOG(foobar(SIN(1)))
    * invoke Function Wizard on that cell (Ctrl+F2)
      LOG(foobar(SIN(1))) is marked in Formula edit field
    * activate Functions page
      LOG(foobar(SIN(1))) is marked in Formula edit field
      Function LOG is selected
    * click Next button
      foobar(SIN(1)) is marked in Formula edit field
      Function ABS is selected
    * click Next button
      foobar(SIN(1)) is overwritten with ABS( )
    * only Cancel solves the problem
    
    foobar() could be any user defined or macro function that have no
    function description in the Formula Wizard.
