    gdb/cli: Remove casts of NULL during assignment.
    
    In the following code:
    
        struct symbol *wsym = (struct symbol *) NULL;
    
    the cast of NULL is redundant, it adds noise, and is just one more thing
    to change if the type of wsym ever changes.  There are a relatively
    small number of places in gdb where the above code pattern is used.
    Usually the cast is removed like this:
    
        struct symbol *wsym = NULL;
    
    This commit updates all the places within the gdb/cli directory where we
    cast NULL during assignment, removing the cast.
    
    gdb/ChangeLog:
    
    	* cli/cli-decode.c (find_cmd): Remove cast of NULL pointer.
