Title: Name clash with an imported function in a module that imports the function to be renamed
Goal: Rename functions named `f' to `reverse' in `export.erl'.
Parameters: [{module,export},{funname,f},{name,reverse}].
Documentation: The tool denies the transformation, because some of the new functions
 would be imported in `import', so they would clash with `lists:reverse/1', which
 is also imported there.
