All right, because we could store both generation number v1 and
generation number v2 in the commit-graph file, and we need to describe
both, the description is now consolidated and in only one place.

A question: do we store 8-byte / 64-bit corrected commit date *directly*,
or do we store corrected commit date *offset* as 8-byte / 64-bit value?
Perhaps we should add the information that [like the EDGE chunk] it is
present only when necessary, and that it is present only when GDAT chunk
is present (it might be obvious, but it could be better to state
this explicitly).

All right, this is the information about two new chunks (with the

overflow-handling chunk).

Minor nitpick: the above point has been accidentally indented one space
more than necessary, and than is indented in other places. Or maybe
that fixes / unifies the formatting... I am not sure.

All right, this just repeats what was written before, or in other words
move existing contents lower/later, just with 'generation number'
replaced by 'topological level' (though it might be not obvious from the
patch because of the latter change).

I think it should be "This property" or "The property", not "The
properties"; it is a single property, a single condition.
We can alternatively say "This condition is fulfilled by both versions...",
or "This condition is true for both versions...".

All right, I agree that we don't need to write about overflow handling
for storing corrected committer dates (generation number v2) as offsets;
this is something format-specific, and this documentation is more about
using commit-graph data. What is present in commit-graph-format.txt
should be enough information.
Sidenote: I wonder if other Git implementations such as JGit, Dulwich,
Gitoxide (gix), go-git have support for the commit-graph file...

This should end in full stop:
+only uses topological levels.
Or maybe we should expand the last sentence a bit:
+only uses topological levels for generation numbers.
Sidenote: it is a good explanation, even if Git can make use of the
property described below that only topmost layers might be missing
corrected commit graph by the construction (so it needs to check only
the top layer).

Perhaps we should explicitly say that when rewriting split commit-graph
as a single file (`--split=replace`) then the newly created single layer
would store corrected commit dates.
