* vm_eval.c (rb_f_caller): caller() method accepts second optional
argument `n' which specify how many frames should return.
For example, `caller(0, 1)' returns only one frame information
which calls caller() method. If there are less than n frame
information, then all frame information are returned. If n is 0,
then always return [].
This fix is part of [ruby-dev:42345] [Ruby 1.9-Feature#3917].
However, performance and features are not enough.
RDoc is also not available.
* test/ruby/test_backtrace.rb: add a test for above.
