* lib/date.rb, lib/date/format.rb (Date._parse): now can take some
hints (its aim must be mainly determination of endianness of date). [experimental] * lib/date.rb, lib/date/format.rb (Date._parse): now completes truncated year as default action. [experimental] * lib/date.rb, lib/date/format.rb: added ::iso8601, ::rfc3339, ::xmlschema, ::rfc2822, ::httpdate, ::jisx0301, #xmlschema, #httpdate. [experimental] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@12833 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
