In my opinion, I'll keep it as close, if not literal to this @subatoi comment.

In addition to that, not only the Linux version should be updated, also Mac (there are more than one installation method) and Windows (if needed) as well.

By the way, there is already a .md talking about "lfs installation verification". It could be interesting to keep the verification quite similar to that.

Sorry I can't be more helpful. I'm on my smartphone with no access to a laptop.

I agree with @aledefault — I misspoke slightly when I singled out line 116. Whilst line 116 does need to change, we also need to change line 48 for macOS.

In both these cases I'd keep it to the one-line change:

Next, make required changes to your global Git config:

In the case of Windows, I think we should leave it as it is, as it's technically correct and users are likely to have a range of different configurations—but I'm very open to discussing that.

We could certainly add a reference to the reusable @aledefault mentioned after this new change, so that could go in this PR or a separate one.

[kdotmanoj]

Thanks @aledefault & @subatoi for your input!
I'll make single line changes on both lines 48 and 116 and raise PR for now.
