hard to read Middleware info from script/about

I found that Middleware infomation from script/about is hard to read.
How about splitting by comma or any other suitable separator?

before:

(snip)
Active Support version    3.0.pre
Middleware                ActionDispatch::StaticRack::LockRack::RuntimeRails::Rack:: ...
(snip)

after:

Middleware                ActionDispatch::Static,Rack::Lock,Rack::Runtime, ...

Thanks,
