ancestor.deepest: ignore ninteresting while building result (issue3984)

ninteresting indicates the number of non-zero elements in the interesting
array, not the number of elements in the final list. Since elements in
interesting can stand for more than one gca, limiting the number of results to
ninteresting is an error.

Tests for issue3984 are included.
