Xml doc comment for ManagedCompiler.GenerateResponseFileCommands is wrong

From ManagedCompiler.cs:

/// <summary> 
/// Returns the command line switch used by the tool executable to specify the response file 
/// Will only be called if the task returned a non empty string from GetResponseFileCommands 
/// Called after ValidateParameters, SkipTaskExecution and GetResponseFileCommands 
/// </summary> 
protected override string GenerateResponseFileCommands() 
{ 
    CommandLineBuilderExtension commandLineBuilder = new CommandLineBuilderExtension(); 
    AddResponseFileCommands(commandLineBuilder); 
    return commandLineBuilder.ToString(); 
} 

The summary comment claims the method returns the command line switch used to introduce a response file. But in fact it seems to return the contents of the response file. It also mentions a GetResponseFileCommands method that doesn't appear to be defined anywhere.
