lib/bigdecimal: errors in comparisons [patch]
$ ruby -r bigdecimal -e 'p BigDecimal.new("1") < nil'
expected: an error like with any other mathematical type:
-e:1:in `<': comparison of BigDecimal with nil failed (ArgumentError)
$ ruby -r bigdecimal -e 'p BigDecimal.new("1") == nil'
expected: false like with any other Ruby object
$ ruby -r bigdecimal -e 'p BigDecimal.new("NaN") < 1'
expected: false, like with any other mathematical comparison
I'll commit the attached patch in a few days (for 1.8 & 1.9) unless there are arguments against it.
ext/bigdecimal/bigdecimal.c: Backport #2349 [ruby-core:26646]; fix comparisons. Also fix a bunch of bugs that lead to broken-ness and failing tests.
test/bigdecimal/test_bigdecimal.rb: Backport #2349 [ruby-core:26646]; added a test suite.
test/ruby/test_exception.rb: The test suite was breaking ZeroDivisionError, which in turn would break bigdecimal/test_bigdecimal.rb. Made a simple fix that keeps that test but does so non-destructively.

Well, a litte inspection shows me that
- 1.9.2dev, 1.8.8dev, and 1.8.7 behave in the same way (as marcandre expected)
- 1.9.1, and 1.8.6 behave as described in the original post
So I suspect 1.9.1 and 1.8.6 are buggy here, both should backport this.
