Thank you for the patch!
(The latest source code is located at https://github.com/tatsuhiro-t/aria2.
We don't use SVN anymore)

I recently added --retry-wait option in upstream source and if user specifies more than 0 to this option,
when aria2 gets 503, it waits for given seconds and retry HTTP request.
The current implementation does not take into account Retry-After field.
So I think it would be good to use the value of Retry-After if it is less than the value in --retry-wait option.
