It is set by default, and --sparse is its opposite option, i.e. it turns revs->dense off.
When revs->dense is turned off, the usual treesame logic does not kick in to rewrite parents in a single strand of pearls (i.e. a stretch of history that solely consists of non-merge commits).

The number of commits in the output will increase by including commits that are irrelevant to explain the history of paths specified by pathspec in revs->prune. The information density decreases as the result, and that is what "sparse" signifies.
