# These tests check that regex engines perform as expected when the search is
# instructed to only search a substring of a haystack instead of the entire
# haystack. This tends to exercise interesting edge cases that are otherwise
# difficult to provoke. (But not necessarily impossible. Regex search iterators
# for example, make use of the "search just a substring" APIs by changing the
# starting position of a search to the end position of the previous match.)
