And my point was that your *whole* argument boils down to "normalization 
is invisible".

When it isn't. It's not invisible for filenames, it's not invisible for 
file contents.

You're trying to claim that normalization cannot matter. I'm just pointing 
out that it sure as hell can. Exactly because lots of things don't 
actually look at data other than as just a Unicode string. They do look at 
the raw format.

And that's true both of file contents and file names.

I'm surprised that you make generalized sweeping statements about how it's 
ok to normalize because normalization is "invisible", and then when I 
point out that that isn't true, you try to limit it.

And no, that normalization is not invisible EVEN IN FILENAMES. If it was, 
git wouldn't ever have noticed it, would it?

I don't know which argument you're talking about. Git (and, btw, Linux) 
does the "ideal" thing (don't screw up peoples data), and it turns out to 
be the "practical" thing too (it can handle a wider range of cases than OS 
X can).

So no, this is not "ideal" vs "practical". They aren't in any conflict 
here.

.. and people have even suggested how. Hide the idiotic OS X choices by 
making a OS X-specific wrapper around readdir() that turns it into NFC.

That's just about the best we can do. We can't *fix* the thing that OS X 
loses information, but a least we can then show the lost information in 
the same form it _probably_ was in originally.

But no, it won't "fix" git on OS X.
