Yup, I agree.

So across filesystems:

 - "git clone /p/a/t/h" falls back to copying;

 - "git clone --local /p/a/t/h" should fail without falling back to
   copying; and

 - "git clone --no-local /p/a/t/h" should work as if file:///p/a/t/h
   was given.

That is much more sensible than making "git clone --no-hardlinks /p/a/t/h"
imply more than what the option really means: we are making a local copy
but do not cheat with hardlinking.
