I'd use SQLite nowadays, because it takes extraordinary care to make sure
that no data is lost short of disk failure. It is considerably more robust
than the underlying filesystem, and runs embedded in its process. It also
means you can readily carry about arbitrary data in additional columns; for
example, you could make line marks persistent, including dot.

Well, I have news for our current leaders and the leaders of tomorrow:
the Bill of Rights is not a frivolous luxury, in force only during
times of peace and prosperity. We don't just push it to the side
