Because of the addition of MR_categorize_data, there is no longer any
control flow in deep_copy.  There is a bit of data manipulation that
is similar in the different functions, but it is nowhere near as
similar as it once was.

So the comment isn't really very useful anymore -- chances are if
you are modifying deep_copy now you *won't* have to modify those
other functions.

That said, I'm happy for the comment to stay or go.
