For local, pass-by-value function arguments (i.e., constant data, or
constant pointers to data), I respectfully disagree. (For "pointers to
constant data", I completely agree that the 'const' info is useful.)

Thank you for catching our mistake now. But I don't think that is
relevant; just because you caught an error doesn't mean that the change
(primarily for consistency's sake) should be avoided entirely.

Unless you have a more convincing argument, this code will remain as-is.
