Using a lazy `?` quantifier lead to poor matching performances and
was not needed technically.
Using `*` instead of `+` lead to a lot of false positives when trying
to write records with an empty value for `data-last-history-steps`.
It is currently unclear how to reach such a case but in the meantime
it is better to allow people to write the record as such rather than
being completely locked with no possibility of saving.
