Oh, we definitely don't want to copy the original huge tables, and we
don't even *want* people to edit those things in the first place.

So generated files are fine. It's not like the source data isn't
public, and yes, the commit message should have a pointer to it and
how to get the source and the generated files. But no, we shouldn't
feel like we should encourage people to be able to generate their own
modified unicode tables.
