[issue6454] Add "example" keyword argument to optparse constructor

[Marcin Kasperski]

I found this bug while looking for suggestions how to add examples to
the optparse help call, but I feel there is a better and more general
solution - just provide some minimal formatting for description: treat
empty line as paragraph separator. Then I would be able to add example
or anything else to the description formatting it as necessary
