      Improve API of recently-added bool vector functions. · ec2c4ee6
      Paul Eggert authored
      The old API had (bool-vector-count-matches A B)
      and (bool-vector-count-matches-at A B I), which gave the
      misleading impression that the two functions were variants, one
      with a location I.  The new API has (bool-vector-count-population A)
      and (bool-vector-count-consecutive A B I) to make the distinction
      clearer.  The first function no longer has a B argument, since the
      caller can easily determine the number of nils if the length and
      number of ts is known.
      * src/data.c (Fbool_vector_count_population): Rename from
      bool_vector_count_matches, and accept just 1 argument.
      (Fbool_vector_count_consecutive): Rename from
      Fbool_vector_count_matches_at.
      * test/automated/data-tests.el: Adjust to API changes.
