Subject: [ruby-core:21137] String marshalling and Marshal version numbers


I just found this "bug"/inconsistency with help of the rack test suite:

>> RUBY_VERSION
=> "1.8.6"
>> Marshal::MAJOR_VERSION
=> 4
>> Marshal::MINOR_VERSION
=> 8
>> Marshal.dump("foo")
=> "\004\b\"\bfoo"

>> RUBY_VERSION
=> "1.9.1"
>> Marshal::MAJOR_VERSION
=> 4
>> Marshal::MINOR_VERSION
=> 8
>> Marshal.dump("foo")
=> "\x04\bI\"\bfoo\x06:\rencoding\"\nUTF-8"

Even if the marshal format itself did not change, the invariant that
same Marshal versions result in the same string does not hold.  Should
MINOR_VERSION be bumped to 5?  (Although I can load the string in 1.8,
but not access the encoding in any way.)
