Yes, makes sense.

I thought about it, of course. But, I am not sure I can
exclude cases when the shell's printf uses 64-bit size_t and
git 32-bit one, or vise-versa. Same way, I cannot say it for
sure for any other software which I might use here instead
of the shell's printf. The only somewhat sure way would be
to use the same compiler, with same settings, which is used
for the production code.

I do not exclude possibility that my reasoning above is
wrong, either in general of specifically for git case. If
there are some examples where it is already used and the
risk of type size mismatch is prevented I could do it
similarly.
