2009-01-19 Bruno Haible <bruno@clisp.org>
Don't include the length in the hash function if all keywords have the
same length.
* src/search.h (Search): Add _hash_includes_len field.
* src/search.cc (Search::prepare): Initialize it.
(Search::count_duplicates_tuple, Search::count_duplicates_multiset,
Search::prepare_asso_values, Search::find_asso_values,
Search::compute_hash): Use it instead of !option[NOLENGTH].
* src/output.h (Output): New field _hash_includes_len. Add it as
constructor argument.
* src/output.cc (Output::Output): Add hash_includes_len argument.
(Output::output_hash_function): Use _hash_includes_len instead of
!option[NOLENGTH].
* src/main.cc (main): Pass _hash_includes_len from Search to Output.
* tests/permut2.exp: Updated expected test result.
* tests/permut3.exp: Likewise.
* tests/permutc2.exp: Likewise.
Reported by Behdad Esfahbod <behdad@behdad.org>.
2009-01-14 Bruno Haible <bruno@clisp.org>
* configure.ac: More consistent m4 quoting.
