I ported simplecov into ruby core for measurement of test coverage.

see. https://github.com/ruby/ruby/pull/708

simplecov is MIT license. we can bundle it to ruby. Can I merge it?

Can we keep it out-of-tree and use it like rubyspec?

I may also extract the terminal-friendly coverage output of yahns
into a standalone gem, its only a few lines:

http://bogomips.org/yahns.git/plain/test/covshow.rb
http://bogomips.org/yahns.git/plain/test/helper.rb

I can make yahns test code CC0/public domain.

Good point.
I implemented make update-coverage task like update-rubyspec.

simplecov can switch terminal-friendly report.
but simplecov shows unreachable code us with html report. It's so useful.
